Question

1/60 + 1/20 Помогите

Answer 1

Пошаговое объяснение:

$\frac{1}{60} + \frac{1}{20} = \frac{1}{60} + \frac{3}{60} = \frac{1 + 3}{60} = \frac{4}{60} = \frac{1}{15}$

Answer 2

1/60 + 1/20 = (1/60 * 3/3) + (1/20 * 3/3) = 3/180 + 9/180 = 12/180 = 1/15

Таким образом, сумма 1/60 и 1/20 равна 1/15.
