Question

3 3/7 + 2 1/5 + 5 4/7 : 5/6

Answer 1

$3 frac{3}{7} + 2 frac{1}{5} + 5 frac{4}{7} div frac{5}{6} = 3 frac{3}{7} + 2 frac{1}{5} + 6 frac{24}{35 } = 5 frac{22}{35} + 6 frac{24}{35} = 12 frac{11}{35}$

(1)

$5 frac{4}{7} div frac{5}{6} = frac{5 times 7 + 4}{7} div frac{5}{6} = frac{39}{7} times frac{6}{5} = frac{234}{35} = 6 frac{24}{35}$

(2)

$3 frac{3}{7} + 2 frac{1}{5} = frac{3 times 7 + 3}{7} + frac{2 times 5 + 1}{5} = frac{24}{7} + frac{11}{5} = frac{120 + 77}{35} = 5 frac{22}{35}$

(3)

$5 frac{22}{35} + 6 frac{24}{35} = 11 frac{22}{35} + frac{24}{35} = 11 frac{46}{35} = 12 frac{11}{35}$
