Question

решите уровнение x:2 2/15=1 9/16

Answer 1

х=1 9/16 * 2 2/15
х= 25/10 * 32/15
(25 и 15 сокращаем на 5, и 16 и 32 сокращаем на 16)
х= 5/1 * 2/3
х=10/3
 х=3 1/3 

Answer 2

х : 2 2/15 = 1 9/16
х : 32/15 = 25/16
х = 25/16 * 32/15
х = (5*2)/(1*3)
х = 10/3
х = 3 1/3
----------------------
Проверка: 10/3 : 32/15 = 10/3 * 15/32 = (5*5)/(1*16) = 25/16 = 1 9/16
