Question

PLEASE HELP IM IN A BIG HURRY

Answer 1

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
