Rewrite a as an improper fraction:

2 3/4 = 11/4

Now you have 11/4 x 4/5

Multiply the two top numbers together and the two bottom numbers together.

11x4 / 4x5 = 44/20 now rewrite as 2 4/20 which can simplify to 2 1/5

Enita is factoring the expression 32 a b minus 8 b. She determines the GCF and writes the factored expression as 8 b (4 a minus
sattari [20]

This shows that the greatest common factor is 8, Hence Venita's error is that she incorrectly determined the GCF.

<h3>Greatest common factor</h3>

Given the following expression

32ab - 8

Find the factors of each terms

32ab = 8 * 4. * a * b

8 = 8 * 1

Since 8 is common to both factors, hence

32ab - 8 = 8(4ab -1)

This shows that the greatest common factor is 8, Hence Venita's error is that she incorrectly determined the GCF.
