9 10 of a sum of money is 45 find the whole amount?

Answer 1

Was that supposed to say "9/10 of a sum of money is 45"? If so, then the answer is "50".

Divide 45 by 9/10, or 0.9. So 45/.9=50

Answer 2

Oh, isn't that a happy little math problem? If 9/10 of a sum is 45, we can find the whole amount by dividing 45 by 9/10, which is the same as multiplying by 10/9. So, 45 multiplied by 10/9 gives us a whole amount of 50.

Answer 3

50
