Question

вот бро помоги пожалуйста ​

Answer 1

Пошаговое объяснение:

№1

10/15 = (10:5)/(15:5) = 2/3

12/18 = (12:6)/(18:6) = 2/3

24/48 = (24:24)/(48:24) = 1/2

20/90 = (20:10)/(90:10) = 2/9

№2

3/4 = (3*5)/(4*5) = 15/20

2/3 = (2*3)/(3*3) = 6/9

№3

0,8 = 8/10 = (8:2)/(10:2) = 4/5

0,44 = 44/100 = (44:4)/(100:4) = 11/25

0,035 = 35/1000 = (35:5)/(1000:5) = 7/200

0,225 = 225/1000 = (225:25)/(1000:25) = 9/40
