1. Sarah's corvette used 30 gallons of

gas from her 50-gallon tank. What

percentage was used?

60% is the answer 60/100

Step-by-step explanation:

30:50 is the ratio

60% is the percentage

as 60/100 is = 30:50

if it was 30% then the gallons held by her car would be 100

because it was 50 we just multiply the top to make a percentage equal to 30 x 2 = 60.

As 50 x 2 = 100

= 60/100
