Answer 1

the answer is (d) 13 43\56

Answer 2

$11\dfrac{1}{7} + 2\dfrac{5}{8}$

Make the denominators the same:

$11\dfrac{1 \times 8}{7 \times 8} + 2\dfrac{5 \times 7}{8 \times 7}$

$11\dfrac{8}{56} + 2\dfrac{35}{56}$

Combine into single fraction:

$13\dfrac{8 + 35}{56}$

$13\dfrac{43}{56}$

Answer: (d) 13 43/56
