Question

a, 37/9 - Y = 6/5 x 15/16
b, Y x 3/15 = 4/5 - 2/3
Giải thích hộ mình nhé. Cám ơn cực cực cực cực kì nhiều ạ

Answer 1

`a)37/9-y=6/5xx15/16`

`37/9-y=9/8`

`y=37/9-9/8`

`y=296/72-81/72=215/72`

`b)y xx3/15=4/5-2/3`

`y xx3/15=12/15-10/15`

`y xx3/15=2/15`

`y=2/15:3/15`

`y=2/15xx15/3=2/3`

Answer 2

a, 37/9 - Y = 6/5 x 15/16

37/9 - Y = 9/8

Y = 37/9 - 9/8

Y = 296/72 - 81/72

Y = 215/72

 

b, Y x 3/15 = 4/5 - 2/3

 Y x 3/15 =  2/15

Y = 2/15 : 3/15

Y = 2/15 x 15/3

Y = 2/3
