Answer 2

Instead of doing (0.75× 8) , she did (2 and one-half minus 0.75)

Step 2

Step-by-step explanation:

Given phrase as expression

4.5 divided by one-fourth + 2 and one-half minus 0.75 times 8

$\Rightarrow \dfrac{4.5}{\frac{1}{4}+2+\dfrac{1}{2}-0.75\times 8$

• Step 1: Simplify 4.5 divided by one-fourth

$\Rightarrow 18+2+\dfrac{1}{2}-0.75\times 8$

• Step 2: simplify 0.75 times 8

$\Rightarrow 18+2+\dfrac{1}{2}-6$Step 2 was wrong by Leticia.

• Step 3: simplify 2 and one-half minus 6

$\Rightarrow 18-3.5$

• Step 4: simplify subtraction

$\Rightarrow 14.5$

Leticia made mistake in step 2

Instead of doing (0.75× 8) , she did (2 and one-half minus 0.75)3
