Which expression is equivalent to the given expression?

8(3/4a)−8
1. 3/4a
2. 6a
3. 8(3/4a - 1)
4. 3/4a -1

Answer 1

8(3/4a)−8 = 8(3/4a - 1)

answer 3. 8(3/4a - 1)

Answer 2

The correct option is 3.

Explanation:

The given expression is

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

The factors of each term are

`8((3)/(4)a)=8* (3)/(4)* a`

`8=8* 1`

The common factor is 8.

Take out the common factor from the given expression.

`8((3)/(4)a-1)`

Therefore option 3 is correct.
