Question

5 insert parentheses into the expression below so the value of the expression is 2. show your work.
$16 + 4 \div 2 \times 5$

Explanation:

Step1: Identify target structure

We need to group terms so the result is 2. Notice $\frac{20}{10}=2$, so we need a numerator of 20 and denominator of 10.

Step2: Group numerator terms

Group the addition to get the numerator: $16 + 4 = 20$

Step3: Group denominator terms

Group the multiplication to get the denominator: $2 \times 5 = 10$

Step4: Combine into fraction

Form the expression: $\frac{16 + 4}{2 \times 5}$

Step5: Verify calculation

Calculate numerator: $16 + 4 = 20$
Calculate denominator: $2 \times 5 = 10$
Divide: $\frac{20}{10} = 2$

Answer:

$\boldsymbol{\frac{16 + 4}{2 \times 5}}$ (or written as $(16 + 4) \div (2 \times 5)$)
