Question

X-8/5=2/4 help pleeeaaaasssee

Answer 1

`(21)/(10)`

Explanation:

x -
`(8)/(5)` =
`(2)/(4)`

x=
`(2)/(4)` +
`(8)/(5)`

Now pay attention.

First, multiply the bottom 2 numbers (4 x 5), that goes on bottom of fraction :
`\frac{}{20}`

Then cross multiply : (4x8) and (2x5) and add them. Put it on top of fraction:

`(32 + 10)/(20)`

`(42)/(20)`

Then reduce fraction:

`(21)/(10)`

I call it the butterfly effect.
