Question

(1/6 +1 /10 +1 /15 ): (3/5-1/3-1/4)

Answer 1

Ответ:

20

Пошаговое объяснение:

1/6+1/10+1/15=5/30+3/30+2/30=10/30=1/3

3/5-1/3-1/4=36/60-20/60-15/60=1/60

1/3:1/60=1/3*60/1=20

Answer 2

$( \frac{1}{6} + \frac{1}{10} + \frac{1}{15} ) \div ( \frac{3}{5} - \frac{1}{3} - \frac{1}{4} ) = \frac{1}{3} \div \frac{1}{60} = \frac{1}{3} \times 60 = 20$
