Помогите с дробями!!! 1) 2/3×1/4= 2) 2/15:1/7= 3) 8×3/4= 4) 1/6:2/3= 5) 4/7:8=

Решите задачу:

$1) \frac{2}{3} * \frac{1}{4} = \frac{2*1}{3*4} = \frac{1}{3*2} = \frac{1}{6}$

$2) \frac{2}{15} : \frac{1}{7} = \frac{2*7}{15*1} = \frac{14}{15}$

$3)8 *\frac{3}{4} = \frac{8*3}{4} =2*3=6$

$4) \frac{1}{6} : \frac{2}{3} = \frac{1*3}{6*2} = \frac{1}{2*2} = \frac{1}{4}$

$5)\frac{4}{7} :8= \frac{4*1}{7*8} = \frac{1}{7*2} = \frac{1}{14}$
