Question

укорочение деталей 15/25, 160/240, 65/143, 108/306, 448/1064, 15•12/30•18
(дада спасайте..)​

Answer 1

Пошаговое объяснение:

15/25 = (15:5)/(25:5) = 3/5

160/240 = (160:80)/(240:80) = 2/3

108/306 = (108:18)/(306:18) = 6/17

448/2064 = (448:56)/(1064:56) = 8/19

15 * 12/30 * 18 = 1 * 12/2 * 18 = 12/2 * 18 = 6 * 18 = 108

Answer 2

Ответ: 3/5, 2/3, 5/11, 8/19, 6/18
