Question

Eric ate $1\frac{2}{7}$ of a pizza, while Lewis ate$1\frac{3}{7}$.
How much did they eat in total?

• A. $3\frac{5}{7}$
• B. $3\frac{1}{7}$
• C. $2\frac{3}{7}$
• D. $2\frac{5}{7}$

Answer 1

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

Total pizza eaten is:$1\frac{2}{7}+1\frac{3}{7}=\left(1+1\right)\left(\frac{2}{7}+\frac{3}{7}\right)=2\left(\frac{2+3}{7}\right)=2\frac{5}{7}$
