Can Someone Please Help Me With Question 2 3 And 4 I Already Did Some class=

Answer :

2a 49.73
Bc 4973\100=49.73
1b 30.4
Bc 3040/100=30.4
3b73.03
Bc 730.3/10=73.03
4b 100
Bc 2820/28.2=100
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
