2a is 49.73
1b is 30.4
3b is 73.03
4b is 100
for these problems you move the decimal to the right for the end answer depending on how many 0’s are in the number you’re multiplying by. for example, 100•__=3040. you would move the 3040 two decimals to the left since there are two 0s in 100, making the answer 30.4
