Question 55374
using rounding

{{{92+89+89+93+91+4+8+2=468}}}


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

{{{62.77*29.8=1870.546}}}

16.132/2.96 =54.5 is not reasonable because the decimal is in the wrong place



{{{16.132/2.96=5.45}}}
