1) what is the difference between the amount of money spent and the amount of money saved in a week?
2) how much does tom save in a week?

Answer 1

Answer:

First, we have to turn 5:4 into two numbers that add to 18.

(Remember ratios are also fractions!)

We can multiply 5:4 by 2 to get 10:8!

10 + 8 = 18
