Question

Tìm x, biết:

( 3/4 + x ) x 50/100 = 8/10

Answer 1

` (3/4 +x) xx 50/100 = 8/10`

`( 3/4 + x) xx 1/2 = 4/5`

` 3/4 + x = 4/5 : 1/2`

` 3/4 + x = 4/5 xx2`

` 3/4 + x = 8/5`

` x = 8/5 - 3/4`

` x = 17/20`

Answer 2

Tìm x, biết:

( 3/4 + x ) x 50/100 = 8/10

( 3/4 + x ) = 8/10 : 50/100

( 3/4 + x ) = 8/5

x = 8/5 - 3/4

x = 17/20.

Answer 3

=>x+3/4=4/5:1/2=4/5x2=8/5

=>x=8/5-3/4=32/20-15/20=17/20

Answer 4

`(3/4+x)xx50/100=8/10`

`(3/4+x)xx1/2=4/5`

`3/4+x=4/5:1/2=4/5xx2=8/5`

`x=8/5-3/4`

`x=32/20-15/20=17/20`

Answer 5

`(3/4+x)xx50/100=8/10`

`(3/4+x)xx1/2=4/5`

`3/4+x=4/5 : 1/2`

`3/4+x=4/5 .2`

`3/4+x=8/5`

`x=8/5 -3/4`

`x=32/20-15/20`

`x=17/20`

Vậy `x=17/20`
