Question

Please hellppppppppp

Answer 1

Ok.
Convert 3/4 to 6/8.

`(9)/(8) - (6)/(8) = (3)/(8)`
There is your answer. 3/8.

Answer 2

`(3)/(4)` is added to x, and the result is
`(9)/(8)`

To find x, you have to subtract the result by the fraction you added with x.

`(9)/(8) - (3)/(4)`

The denominators aren't the same. The LCM of 4 and 8 is 8, so change the fractions so that they both have a denominator of 8.

`(9 * 1)/(8 * 1) = (9)/(8)`

`(3 * 2)/( 4 * 2) = (6)/(8)`

Your new equation is:

`(9)/(8) - (6)/(8)`

Subtract:

`(9)/(8) - (6)/(8) = (3)/(8)`

ANSWER:
`(3)/(8)`
