Question

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

Explanation:

Step1: Group terms for target value

We need to create a numerator of 20 and denominator of 10 to get 2, so group the addition and the multiplication:
$(16 + 4) \div (2 \times 5)$

Step2: Calculate numerator first

Compute the sum inside the first parentheses:
$16 + 4 = 20$

Step3: Calculate denominator next

Compute the product inside the second parentheses:
$2 \times 5 = 10$

Step4: Divide numerator by denominator

Divide the two results to get the target value:
$\frac{20}{10} = 2$

Answer:

$(16 + 4) \div (2 \times 5)$
