A bucket contains 4 1/2 gallons of water. If Trudy adds 5 3/8 gallons more, how many gallons will there be in all?
Anna11 [10]

Answer:

9 7/8 gallons of water.

Step-by-step explanation:

When you convert both mixed numbers into improper fractions with the same denominator, you can add the two fractions

5 3/8 as an improper fraction is 43/8, and 4 1/2 becomes 9/2. Multiply 9/2 by 4 to get the same denominators for both fractions.

43/8 + 36/8 = 79/8

79/8 as an improper fraction is 9 7/8.
