Im in a big hurry 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. who used the greatest amount of oil from the can? show your work and explain your answer in words.

First, change the fraction (decimal and percent) into gallon
Martha used 17% of the total oil, that means
Martha = 17% × 8 gallons
Martha = 0.17 × 8 gallons
Martha = 1.36 gallons

Brett used 0.18 of the total oil
Brett = 0.18 × 8 gallons
Brett = 1.44 gallons

Mike used 0.7 gallons

Second, compare the number of gallon they used
1.36
1 acts as ones
3 acts as tenths
6 acts as hundreths

1.44
1 acts as ones
4 acts as tenths
4 acts as hundreths

0.7 or 0.70
0 acts as ones
7 acts as tenths
0 acts as hundreths

Compare the ones, 1.44 and 1.36 both have 1 as the ones, however 0.7 has 0 as ones. Because 1 is greater than 0, 1.44 and 1.36 are greater than 0.7.
Now compare the tenth, 1.44 has 4 as the tenths, and 1.36 has 3 as the tenths. Because 4 is greater than 3, 1.44 is greater than 1.36.
1.44 > 1.36 > 0.7
Brett > Martha > Mike
Brett used the greatest amount of oil
