Question

George ate 2/ 3 of a container of Chinese food. Silvia ate 1/ 5 of the same container of Chinese food. What fraction of the container of Chinese food did they eat together?

Answer 1

Answer: Fraction of the container of Chinese food they eat together =
`(13)/(15)`

Explanation:

Given, Fraction of Chinese food eaten by George =
`\frac23`

Fraction of Chinese food eaten by Silvia =
`\frac15`

Fraction of the container of Chinese food they eat together =
`\frac23+\frac15 =(2*5+3*1)/(3*5)`

`=(10+3)/(15)=(13)/(15)`

Fraction of the container of Chinese food they eat together =
`(13)/(15)`
