Question

This question is kinda confusing. Its in chinese but heres the translation:" Mom gave Feifei some rice, FeiFei used 4/5kg of it to make rice balls, there was still 2/3 kilograms of rice left. How many kg of rice does Feifei have originally?​

Answer 1

(22/15) kg or 1 7/15 kg

Explanation:

Let x be the amount of rice Mom gave to Feifei, in kg.

"used 4/5kg of it to make rice balls, there was still 2/3 kilograms of rice left"

x - (4/5) = (2/3) [all units in kg]

x = (4/5) + (2/3)

x = (4/5)*(3/3) + (2/3)*(5/5)

x = (12/15) + (10/15)

x = (22/15) kg or 1 7/15 kg
