Question

Martha, Brett, and Mike are competing in a cooking competition. They all used different amounts of oil from a can containing 8 gallons of oil. Martha used 17% of the total oil in the can. Brett used 0.18 of the total oil in the can. Mike used 0.7 gallon of the total oil in the can.
My question is how would you turn those decimals into percentages?

Answer 1

Hi!

You can turn the decimals into percentages by multiplying the decimal by 100. Multiplying a decimal by 100 turns the decimal into a percentage. So for 0.18, we would do this:
$0.18 \times 100 = 18\%$
This would give us the percentage, which would be 18%.

We would do the same for 0.7, which would look like this:
$0.07 \times 100 = 70\%$
Which would give us our percentage, which would be 70%.

On conclusion, the formula for turning a decimal into a percentage is:
$decimal \times 100 = \%$
Hope this helps! Good luck!
