Answer:
a) 5
b) 469.213
c) 37.163
d) 0.003702
e) 3971.32
f) 78.473
Let's solve this:
a. There is no decimal between the 5 and 0 in 50. It should be 5.
b. Didn't line up the decimal points. The answer should be 469.213
c. To solve this problem correctly, you must make 100 to 100.000. Then if you solve it, the answer would be correct. It should be 100.000 - 62.837=37.163
d. The decimal point is placed at the wrong place. It should be 6 places to the left, because there are three digits after the decimal point in each number (3+3=6). The answer should be 0.003702
e. To solve this problem correctly, you must make 4006.3 to 4006.30. Then if you solve it, the answer would be correct. It should be 4006.30 - 34.98 = 37.163= 3971.32
f. The decimal points are not lined up. So the answer is way off. It should be 78.473
I hope this helps ;)
