Answer:
Yes, he can.
Step-by-step explanation:
Harper has two cans of paint that he would like to combine into one can.
One can contains 6.11 ounces and the other can contains 22.7 ounces.
The total quantity of paint he has is:
6.11 + 22.7 = 28.81 ounces
Since 28.81 ounces is lesser than 29 ounces, he can put both cans of paint into the 29 ounce can of paint.
