Question

A recipe requires 1 2/3 cups of sugar. If Mrs. Marina is going to make one half of the recipe , then how much sugar does she need

Answer 1

5/6 cups

Explanation:

This question is essentially asking us to divide the number 1 2/3 by 2. We can perform this operation by converting our number to a single fraction and then multiplying this number by the inverse of the divisor.

1. 
   `1(2)/(3) =1+(2)/(3) = (3)/(3) +(2)/(3)=(3+2)/(3) =(5)/(3)\\` (put in single fraction form)
2. 
   `(5)/(3) /2 = (5)/(3) * (1)/(2) = (5*1)/(2*3) = (5)/(6)` (multiply by inverse)
