е) y=6,4

Пошаговое объяснение:

y:16/5=9/2:9/4

y×5/16=9/2×4/9 (девятки сокращаются и 4 и 2 сокращаем на 2)

y×5/16=2

у=2/1:5/16

Пошаговое объяснение:

у* 2 1/4= 3 1/5 * 4 1/2

у= 16/5 * 9/2 : 9/4

у=16*9*4/5*2*9

у=16*2/5=32/5= 6 2/5=6.4

2 2/3*(х+0.06)=0.24*1 7/9

х+0.06= 24/100* 16/9: 8/3

х+0.06= 6/25* 16/9: 8/3

х+0.06= 6*16*3/25*9*8

х+0.06= 6*2/25*3

х+0.06= 2*2/25

х+0.06= 4/25

х+0.06= 0.16

х=0.16-0.06

х=0.1
