Question 55374: estimate.state your method.(rounding,front-end,or clustering)
91.7 + 88.6 + 89.1 + 92.5 + 90.6
3.9 + 8.1 + 2.06
Detemine whether each product or quotient is resonable.If it is not resonable,find a resonable result.
62.77(29.8)=187.0546
16.132/2.96 = 54.5
Please and thank-you

using rounding
91.7 becomes 92 because the number in the tenths place is greater than 5
88.6 becomes 89 because the number in the tenths place is greater than 5
89.1 becomes 89 because the number in the tenths place is less than 5
92.5 becomes 93 because the number in the tenths place is 5 or greater
90.6 becomes 91 because the number in the tenths place is greater than 5
3.9 becomes 4 because the number in the tenths place is greater than 5
8.1 becomes 8 because the number in the tenths place is less than 5
2.06 becomes 2 because the number in the tenths place is less than 5
then you just add them up to get your estimate by rounding
Detemine whether each product or quotient is resonable.If it is not resonable,find a resonable result.
62.77(29.8)=187.0546 is not reasonable because the decimal is in the wrong place
16.132/2.96 =54.5 is not reasonable because the decimal is in the wrong place
