Answer 1

\(\dfrac{6}{7}+\dfrac{5}{8}=\dfrac{48}{56}+\dfrac{35}{56}=\dfrac{83}{56}\)

\(\dfrac{36}{12}-\dfrac{5}{3}=\dfrac{9}{3}-\dfrac{5}{3}=\dfrac{4}{3}\)

Answer 2

\(\dfrac{6}{7}+\dfrac{5}{8}=\dfrac{48}{56}+\dfrac{35}{56}=\dfrac{83}{56}\\\dfrac{36}{12}+\dfrac{5}{3}=\dfrac{36}{12}+\dfrac{20}{12} =\dfrac{56}{12}=\dfrac{14}{3}\)

Answer 3

6/7 + 5/8 = 48/56 + 35/56 = 83/56

36/12 - 5/3 = 36/12 - 20/12 = 16/12 = 4/3

Answer 4

36/12 − 5/3 = 9/3 − 5/3 = 4/3
