Multiplication is a math operation that helps us find the total number when we have a certain number of groups of another number. When it comes to multiplication of whole numbers by fractions, it can be a little tricky for kids to understand, but with some practice and the right approach, it can be made easy.

First, let’s review what a fraction is. A fraction is a way to express a part of a whole. It is made up of two parts: the numerator (the top number) and the denominator (the bottom number). For example, if you have a pizza and you want to share it with two friends, you can express that as a fraction. You would say, “I have half a pizza” and write it as 1/2. This means that you have one out of two equal parts of the pizza.

Now, let’s talk about multiplication. Multiplication is an operation that allows us to find how many objects we have in total when we have a certain number of groups of another number of objects. For example, if you have two groups of three cookies, you can say, “I have six cookies” and write it as 2 x 3 = 6.

When we multiply a whole number by a fraction, we are finding how many parts of the whole number the fraction represents. For example, if we have 4 apples and we want to find out how many apples make up half of the total, we can write it as 4 x 1/2.

To multiply a whole number by a fraction, we can use a special method called “canceling before multiplying.” This means we divide the whole number by the denominator of the fraction, and then multiply the result by the numerator of the fraction.

For example, let’s go back to our 4 apples and half of the total. We want to multiply 4 by 1/2. To do this, we first divide 4 by 2, and then multiply the result by 1.

4 ÷ 2 = 2 2 x 1 = 2

This means that half of the total number of apples is 2 apples.

It’s important to note that when we multiply a whole number by a fraction, the result is still a whole number. However, we can also write the answer in simplest form. This means that we divide both the numerator and denominator by any common factors they have. For example, in our answer of 2, we don’t need to simplify it since it’s already a whole number.

Let’s now practice multiplying whole numbers by fractions. Imagine we have 8 pieces of candy and we want to find out how many pieces make up 3/4 of the total. We can start by dividing the whole number by the denominator of the fraction, which is 4.

8 ÷ 4 = 2

Now, we multiply the result by the numerator of the fraction, which is 3

2 x 3 = 6

This means that 3/4 of the total number of candy is 6 pieces.

Another example would be to take 8 pencils and find out how many pencils make up 1/2 of the total. By dividing 8 by 2 and multiplying the result by 1 we find that 1/2 of the total pencils is 4.

8 ÷ 2 = 4 4 x 1 = 4

In conclusion, multiplication of whole numbers by fractions can be a tricky concept, but with the help of the “canceling before multiplying” method and writing the answer in simplest form, it can be made easy for kids to understand. With practice and a clear understanding of fractions and multiplication, kids will be able to multiply whole numbers by fractions with confidence
