Step-by-step explanation: I also taking the exam :D calisthenics rok

Answer 2

The steps 2 and 3 are required.

The correct steps are

2. Divide the difference by the original number.

3. Multiply the quotient by 100 to change it from a decimal to a percent.

The second step will be

$\dfrac{|\text{Original}-\text{New}|}{\text{Original}}$

The third step will be

$\dfrac{|\text{Original}-\text{New}|}{\text{Original}}\times 100$

So, the second step will be Divide the difference by the original number.

The third step will be multiply the quotient by 100 to change it from a decimal to a percent.
