Question

A bag contains $5\frac{1}{6}$ kg flour. Ruby used $3\frac{1}{3}$ kg to bake a cake. How much flour is left in the bag?

• A. $1\frac{5}{6}$ kg
  
• B. $1\frac{1}{6}$ kg
  
• C. $2\frac{2}{3}$ kg
  
• D. $2\frac{5}{6}$ kg

Answer 1

The correct option is A

$1\frac{5}{6}$ kg

Flour available $=5\frac{1}{6}=\frac{31}{6}$ kg
Flour used $=3\frac{1}{3}=\frac{10}{3}$ kg
Flour left $=\frac{31}{6}-\frac{10}{3}=\frac{31-20}{6}=\frac{11}{6}=1\frac{5}{6}$ kg
