Question

Пожалуйста помогите)))

Answer 1

$frac{1}{12} + frac{3}{4} = frac{1}{12} + frac{9}{12} = frac{10}{12} = frac{5}{6}$

__________

$2 frac{1}{4} div frac{1}{6} = frac{9}{4} div frac{1}{6} = frac{9}{4} times frac{6}{1} = frac{54}{4} = frac{27}{2}$

27 / 2 = 13 1/2

__________

$2 - 1frac{3}{7} = frac{2}{1} - frac{10}{7} = frac{14}{7} - frac{10}{7} = frac{4}{7}$

__________

$12 times frac{3}{4} = 3 times 3 = 9$
