Question

Jon has $45.00. He plans to spend 4/5 of his money on sports equipment. How much will h spend?

Answer 1

For this, you simply divide 45/5 which gets you 9 and you multiply that by 4 which gets you 36$

Answer 2

An easy way to solve this is to use a proportion

the proportion would be as follows:

x/45  = 4/5

Because in the fraction 4/5, 5 is the whole number equaling 1 whole piece
And in the problem, the whole amount of money Jon has is $45

Now to solve, we can simply divide 45 by 5, and multiply 4 by that answer

So 45/5 = 9

5 x 9 = 45
4 x 9 = 36

Completed proportion: 36/45 = 4/5

x = 36

Answer: Jon will spend $36 on sports equipment

I hope this helps!
