Nine tenths of a sum of money is 45. Find the whole amount

Answers

Answer 1
Answer: If you would like to know the whole amount of money, you can calculate this using the following steps:

nine tenths of a sum of money is 45
9/10 * x = 45     /*10
9 * x = 45 * 10   /9
x = 45 * 10 / 9
x = 50

Result: Nine tenths of 50 is 45.
Answer 2
Answer: The answer is 50.

First do 45 divided by 9 which is 5 then times by 10 results in 50.

A way to check this is by then finding 1/10 of 50 which is 5 then X by 9 is 45, which is what you originally started with.
