How to Divide Fractions by Whole Numbers? A lot of kids find division to be a complex arithmetic operation and things get very complicated when the division is taken to an advanced level where fractions get involved. Dividing fractions by whole numbers can get difficult but taking a step-by-step approach can help in countering the difficulties. Step 1 - Converting the whole number into a fraction. To convert the whole number into fraction, you must change the division operation into the multiplication operation. Example; 5/7 ÷ 5 To convert 5 into a fraction you change division into multiplication; 5/7 × 1/5 Step 2 - Multiply the Final Fractions - Multiply the numerator of both the fractions, and multiply the denominators of both fractions. (5 × 1) / (7 × 5)= 5/35 Step 3 - Simplification - The next step is to simplify the final fraction to get the right answer. 5/35 can be simplified to 1/7

How to Spot the Division of Fractions in a Word Problem
When you are tackling any story or situational based math problem your focus should be on identifying all the details first. Once you understand the overall process of what is happening, you just need to drop the numbers into the process to solve them. If we spot any of the following keywords, you bet the farm that division is taking place to solve the problem: average, cut, even, every, out of, ratio, share, and split. For example, if we were examining the problem: Jeanne was bought chocolates to share with her favorite teachers. If she purchased 3/4 pounds of chocolate and needed to share them between her 3 favorite teacher, how much chocolate would each teacher receive. The concept here is that an amount of chocolate will be shared between people (teachers). The word "share" tells us which operation we are working with. We are looking for the amount of chocolate each person would receive, if it were shared equally. If we were to write this as an equation it would resemble: amount of chocolate = all chocolate ÷ number of people. Like I said, we now just have to put the numbers in: amount of chocolate = 3/4 pounds ÷ 3. In the end each teacher would receive a quarter pound of chocolate.
