Question

A group of people are having a fund raiser for a children's hospital. Fiona raised 2/7 of the money and Patrick raised 3/5 of the money. The rest of the money was raised by the rest of the group. What fraction of the money was raised by Fiona and Patrick? *

Answer 1

31/35

Explanation:

The fraction of the money raised by Fiona and Patrick is the sum of the fractions given for the money raised by both of them. Given that Fiona raised 2/7 of the money and Patrick 3/5, the sum of these 2 fractions

= 2/7 + 3/5

make the lowest common multiple of the denominators the base and multiply the numerators by it

= (10 + 21)/35

= 31/35
