There are 3 simple steps to multiply fractions 1 Multiply the top numbers the numerators 2 Multiply the bottom numbers the denominators 3 Simplify the fraction if needed Example 1 2 2 5 Step 1 Multiply the top numbers 1 2 2 5 1 2 2 Step 2 Multiply the bottom numbers 1 2 2 5 1 2 2 5 2 10 Step 3 The denominator will always stay the same when making improper fractions Multiply the denominator by the whole number 4 1 and add that answer to the current numerator 3 4 1 3 7 For 7 and 1 5 multiply the denominator by the whole number 5 7 and add that answer to the current numerator 1 5 7 1 36

3 years ago The easiest way to think about multiplying fractions by whole numbers is to multiply the numerator of the fraction by your integer and then bring over the deonominator 3 4 8 can be thought of as 3 8 4 or 24 4 or 6 1 2 7 is 1 7 2 or 7 2 6 23 3 is 6 3 23 or 12 23 Step 1 Turn the Whole Number Into a Fraction Your first step is turning the whole number into its own fraction This is easy you just give it a denominator of 1 So from our example 6 becomes 6 1 This is true because 6 divided into 1 group still equals 6 This is true for any whole number 3 3 1 17 17 1 etc Now we have x 6 1
We have two steps to when multiplying whole numbers by fractions and they are as follows Repeated Addition Method Repeated addition is the process of adding equal groups and multiplication is another name for it If the same number appears again and again we can write it as multiplication 2 2 2 2 2 2 2 2 times 7 14 Step 1 Multiply the numerators This will be the numerator of the new fraction Step 2 Multiply the denominators This will be the denominator of the new fraction Step 3 Simplify the resulting fraction by reducing it to the lowest term if needed Before we go over some examples there are other ways to mean multiplication
