select all of the expressions that have the same value as $380 \div 58$
$38000 \div 580$
$3800 \div 580$
$3.86 \div 0.58$

Explanation:

Problem 4:

Step1: Set up percentage formula

$\text{Percent Completed} = \frac{\text{Completed Miles}}{\text{Total Goal Miles}} \times 100$

Step2: Plug in given values

$\text{Percent Completed} = \frac{5}{16} \times 100$

Step3: Calculate the result

$0.3125 \times 100 = 31.25$

Problem 12:

Step1: Find base value

$380 \div 58 \approx 6.5517$

Step2: Check first expression

$38000 \div 580 = \frac{380 \times 100}{58 \times 10} = \frac{380}{58} \times 10 = 6.5517 \times 10 = 65.517$ (Note: This does NOT match the base value, the checkbox in the image is incorrect here)

Step3: Check second expression

$3800 \div 580 = \frac{380 \times 10}{58 \times 10} = \frac{380}{58} \approx 6.5517$ (Matches base value)

Step4: Check third expression

$3.80 \div 0.58 = \frac{380 \div 100}{58 \div 100} = \frac{380}{58} \approx 6.5517$ (Matches base value)

Corrected Answer for Problem 12: B. $3800 \div 580$, C. $3.80 \div 0.58$

Answer:

1. 31.25
2. A. $38000 \div 580$, B. $3800 \div 580$, C. $3.80 \div 0.58$
