To find out how many more gallons of gas Nicole used on Saturday than on Sunday, we need to subtract the amount used on Sunday from the amount used on Saturday.
2 4/5 - 1 1/2
First, we convert both mixed numbers into improper fractions:
2 4/5 = (5*2 + 4)/5 = 14/5
1 1/2 = (2*1 + 1)/2 = 3/2
Now, we can subtract the fractions:
14/5 - 3/2
To subtract these fractions, we need to find a common denominator. In this case, the least common denominator is 10, so we will convert the fractions to have this denominator:
14/5 = 28/10
3/2 = 15/10
So the subtraction is:
28/10 - 15/10 = 13/10
Now, we can convert the improper fraction back to a mixed number:
13/10 = 1 3/10
Therefore, Nicole used 1 3/10 more gallons of gas on Saturday than on Sunday.
