Question

George has 64 baseball cards. He gives 28 of them to his brother. Which method shows a way to find 64 - 28?

a. 28 + 2 = 30
30 + 30 = 60

b. 64 - 4 = 60
60 - 4 = 56
56 - 20 = 36

c. 64 - 40 = 24
64 + 8 = 32

d. 64- 4 = 60
60 - 8 = 52
52 - 20 = 32

Answer 1

The correct method to find out 64 minus 28 is to break down the subtraction into parts, subtracting 4 to reach 60, then 20 to reach 40, and finally subtract 8 to get 32.

Step-by-step explanation:

To find the solution for 64 - 28, we can break down this subtraction problem into simpler steps. The method that correctly shows a way to find 64 - 28 is:

d. 64 - 4 = 60
60 - 20 = 40
40 - 8 = 32

By breaking down the subtraction into smaller, more manageable parts, particularly through subtracting multiples of 10 and then the remaining units, we arrive at the correct answer in a way that is easier to perform in one's head.
