Question

Eric ate $1\frac{2}{7}$ pizzas, while Lewis ate $1\frac{3}{7}$. How many pizzas did they eat in total?

• A. $11\frac{5}{7}$
• B. $3\frac{5}{7}$
• C. $2\frac{3}{7}$
• D. $2\frac{5}{7}$

Answer 1

The correct option is D $2\frac{5}{7}$

Total number of pizzas eaten $=1\frac{2}{7}+1\frac{3}{7}=(1+1)(\frac{2}{7}+\frac{3}{7})=2\left(\frac{2+3}{7}\right)=2\frac{5}{7}$

Hence, Eric and Lewis ate $2\frac{5}{7}$ pizzas in total.
