Question

First round to the nearest whole number.
10.3 + 1.46
11.53 + 7.23

so i believe 10 + 1.50 = 1.60??
then 11.50 + 7.20 is 18.70 ?

Use front-end estimation to estimate each sum.
4.39 + 9.57
3.62 + 2.31

would it be 4.40 + 10.00 = 14.40
and 3.60 + 2.30 = 5.90

Use compatible numbers to estimate each quotient.
103.6 divided by 9.72
3.963 divided by 1.79

im stuck on rounding 103.6 but i believe 9.72 is rounded to 9.70
im also stuck on 3.963 but 1.79 would round to 1.80?

Answer 1

Your question started with "round to the nearest whole number."
A whole number has NO decimals...
So... 10.3 is 10 and 1.46 is 1...
