Question

12 7/11+(4 4/11-2 2/7)

Answer 1

$12 \frac{7}{11} + (4 \frac{4}{11} - 2 \frac{2}{7} ) = 14 \frac{5}{7}$

$1)4 \frac{4}{11} - 2 \frac{2}{7} = 4 \frac{28}{77} - 2 \frac{22}{77} = 2 \frac{6}{77}$

$2)12 \frac{7}{11} + 2 \frac{6}{77} = 12 \frac{49}{77} + 2 \frac{6}{77} = 14 \frac{55}{77} = 14 \frac{5}{7}$
