Add. Explain how you got your answer. 5.52 + 1.88
|
5.52+1.88=7.40 I got this answer by first adding the decimals together (0.52+0.88= 1.40), then adding the wholes together (5+6=6), then by adding those two answers together (1.40+6=7.40)
*other explanations are acceptable as long as they relate to a written method |
|
|
Subtract. Explain how you got your answer. 60.75 - 49.97
|
60.75-49.97=10.78. I did this by adding 0.03 to 49.97 to make it 50. Since I did that I had to add 0.03 to 60.75 also to make it 60.78. Then I did 60.78-50 which equals 10.78.
