Mark and Tony share a sum of money in the ratio 3:5. What fraction of the money did Tony ratio receive?

Part A is 3/8 of the whole

Part B is 5/8 of the whole

the Whole = A + B is the denominator:

Whole = 3 + 5 = 8

Part A = 3 and Part B = 5 are numerators for each fraction.

The fractions are then:

3/8 and 5/8

Meaning:

Part A is 3/8 of the whole

Part B is 5/8 of the whole
