Question

HELPPP!!! And explain please.

Answer 1

Answer:

After correcting error of Mia and solving the expression$0.38 \times 3 \div(-1/20)\times5\div(-8)$ we get 14.25

Step-by-step explanation:

The given expression is:$0.38 \times 3 \div(-1/20)\times5\div(-8)$

First I solve the expression, and then will point the error

$0.38 \times 3 \div(-1/20)\times5\div(-8)\\Converting \ \div \ sign \ into \ \times the \ term \ is \ inverted\\=0.38 \times 3 \times(-20)\times5\times(-1/8)\\=0.38\times 3 \times-20\times5\times-1/8\\=1.14 \times-20\times5\times-1/8\\=-22.8\times5\times-1/8\\=-114\times-1/8\\=\frac{-114}{-8}\\=14.25$

So, the mistake Mia did was when she inverted division sign into multiplication, she didn't invert the term next to division sign.

The step she did was: $0.38 \times 5 \times(1/20)\times3\times(-8)$

While the correct step was: $0.38 \times 3 \times(-20)\times5\times(-1/8)$

After correcting error of Mia and solving the expression$0.38 \times 3 \div(-1/20)\times5\div(-8)$ we get 14.25
