Option C:

The equivalent expression is $8\left(\frac{3}{4} a-1\right)$ .

Solution:

Given expression:

$$8\left(\frac{3}{4} a\right)-8$

To find which expression is equal to the given expression:

Option A: $\frac{3}{4}a$

After cancelling 4 and 8, we get

$8\left(\frac{3}{4} a\right)-8=2\left(3a)-8$

= 6a – 8

This is not equivalent expression.

Option B: 6a

By the above calculation, we get 6a –8.

This is not equivalent expression.

Option C: $8\left(\frac{3}{4} a-1\right)$

$8\left(\frac{3}{4} a\right)-8$

Two terms have 8 common, so take 8 outside.

$8\left(\frac{3}{4} a\right)-8=8\left(\frac{3}{4} a-1\right)$

This is the equivalent expression.

Option D: $\frac{3}{4} a-1$

By the above calculation, we get $8\left(\frac{3}{4} a-1\right)$ .

This is not equivalent expression.

Hence Option C is the correct answer.

The equivalent expression is $8\left(\frac{3}{4} a-1\right)$ .
