Hello, friends! Today, we’re going to have some fun with fractions. We’ll learn how to multiply and divide them. Are you ready? Let’s dive in!
Before we start, let’s remember what fractions are. A fraction has two parts: the top number is called the numerator, and the bottom number is called the denominator. Now that we know this, let’s get started!
Multiplying fractions is super easy! Here’s how you do it: to find the new numerator, you multiply the numerators of the two fractions. To find the new denominator, you multiply the denominators of the two fractions. That’s it!
Let’s try an example. We want to multiply one-half by three-fifths. First, we multiply the numerators: 1 times 3 equals 3. Next, we multiply the denominators: 2 times 5 equals 10. So, one-half multiplied by three-fifths equals three-tenths. Great job!
Now, let’s see if you can do this one: two-thirds multiplied by one-fifth. Multiply the numerators: 2 times 1 equals 2. Then, multiply the denominators: 3 times 5 equals 15. So, two-thirds multiplied by one-fifth equals two-fifteenths. Did you get it right? Awesome!
Dividing fractions is just as fun! Here’s the trick: when you divide fractions, you cross-multiply. This means you multiply the numerator of the first fraction by the denominator of the second fraction to get the new numerator. Then, you multiply the denominator of the first fraction by the numerator of the second fraction to get the new denominator.
Let’s divide three-fifths by one-half. First, multiply the numerator of the first fraction by the denominator of the second fraction: 3 times 2 equals 6. That’s our new numerator. Next, multiply the denominator of the first fraction by the numerator of the second fraction: 5 times 1 equals 5. That’s our new denominator. So, three-fifths divided by one-half equals six-fifths. Excellent!
Try this one: one-fifth divided by one-third. Multiply the numerator of the first fraction by the denominator of the second fraction: 1 times 3 equals 3. Then, multiply the denominator of the first fraction by the numerator of the second fraction: 5 times 1 equals 5. So, one-fifth divided by one-third equals three-fifths. Well done!
Now you know how to multiply and divide fractions like a pro! Keep practicing, and you’ll get even better. Remember, learning can be fun, and there’s always more to discover. See you next time!
Fraction Art: Create a piece of art using fractions! Gather some colored paper, scissors, and glue. Cut the paper into different shapes like circles, squares, and triangles. Use fractions to describe each shape. For example, if you cut a circle into 4 equal parts and color 1 part, you have colored one-fourth of the circle. Try to create a picture using different fractions and explain your artwork to a friend or family member.
Fraction Cooking: With the help of an adult, try a simple recipe that involves fractions. For example, make a fruit salad using different fruits. If the recipe calls for 1/2 cup of strawberries and 1/4 cup of blueberries, measure them out and mix them together. Discuss how you used fractions to make the recipe and how changing the fractions would change the amount of each ingredient.
Fraction Hunt: Go on a fraction hunt around your home or classroom. Look for items that can be divided into fractions, such as a pizza, a chocolate bar, or a set of blocks. Write down the fractions you find and explain how you divided each item. For example, if you have a chocolate bar with 8 pieces and you eat 2, you have eaten two-eighths of the bar. Share your findings with your classmates or family.
Sure! Here’s a sanitized version of the YouTube transcript:

Hello again, friends! We continue practicing operations with fractions. Today, we’re going to learn how to multiply fractions.
First, let’s recap the parts of a fraction: the top number is the numerator, and the bottom number is the denominator. Now we’re ready to start!
Do you know how to multiply fractions? It’s really easy! Pay close attention. To find the numerator, we multiply the numerators, and to find the denominator, we multiply the denominators. This means that to multiply fractions, we multiply the two numerators together and the two denominators together. Easy, right? Told you!
Let’s look at an example. We need to multiply one-half by three-fifths. To do that, we’re going to multiply the numerators: one by three, which equals three. Then we’re going to multiply the denominators: two by five, which equals ten. So, one-half multiplied by three-fifths equals three-tenths. Well done!

Did you understand that? Shall we look at another example? Let’s see if you can solve this operation: two-thirds multiplied by one-fifth equals… Two by one equals two, and three by five equals fifteen. Did you get that right? Amazing! Congratulations! Now you know how to multiply fractions. You’re a real expert! See you in the next video.
Hello again, friends! We continue practicing operations with fractions. Today, we’re going to learn how to divide fractions. First, let’s recap quickly the parts of a fraction: the top number is the numerator, and the bottom number is the denominator. Now we’re ready to start!
Dividing fractions is fun! Do you want to know how it’s done? When we divide fractions, to find the numerator, we multiply the numerator of the first fraction by the denominator of the second fraction. To find the denominator, we multiply the denominator of the first fraction by the numerator of the second fraction. This means that to divide fractions, we cross-multiply them.
Did you understand how it’s done? Let’s look at the next example. We need to divide three-fifths by one-half. To find the numerator of the product, we multiply the numerator of the first fraction by the denominator of the second fraction, meaning three by two, which equals six. The numerator of the product is six.
Now, to find the denominator of the product, we multiply the denominator of the first fraction by the numerator of the second fraction, meaning five by one, which equals five. The denominator of the product is five. So, three-fifths divided by one-half equals six-fifths. Excellent!
Let’s look at the next example. Would you like to try doing this one yourself? One-fifth divided by one-third equals… Let’s find out if you got it right. One-fifth divided by one-third equals three-fifths.
Congratulations! Now you know how to divide fractions. You’re a real expert! See you in the next video.
