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 = $\dfrac{13}{15}$

Step-by-step explanation:

Given, Fraction of Chinese food eaten by George = $\dfrac23$

Fraction of Chinese food eaten by Silvia = $\dfrac15$

Fraction of the container of Chinese food they eat together = $\dfrac23+\dfrac15 =\dfrac{2\times5+3\times1}{3\times5}$

$=\dfrac{10+3}{15}=\dfrac{13}{15}$

Fraction of the container of Chinese food they eat together = $\dfrac{13}{15}$
