Answer 8

Round each number to the nearest hundredth.
means
now we have to decide whether to keep 86.34500 as
86.34
or
86.35

if the number to the right of the 4 (i.e. the thousandths place) is 5 or bigger
we make the 4 a 5 (we make the 4 one bigger)

What is the best estimate for the sum of 317.38 82.21?



A.
410


B.
400


C.
399


D.
390

Answer 18

round to the nearest whole number...
anything to the left of the decimal is a whole number.
317.38 would then round to 317....because .38 rounds to 0....if it would have been greater or equal to .50, then you would have rounded up to 318.

Now try and round 82.21 to the nearest whole number and what do you get ?

What is the best estimate for the difference of 483.51 – 246.17?



A.
230


B.
237.3


C.
237.4


D.
238

Answer 41

483.51 --- the tenths place would be the number right after the decimal....the 5, and since the number after the 5 is smaller then 5, you would round down. So this number would be : 483.5

246.17 to the nearest tenths is 246.2

483.5 - 246.2 = 237.3

Answer 42

oops...let me rephrase...483.51 -- since the number after the 5 is less then 5, you would keep it the same and not round up

Answer 43

I believe with these types of problems, you round before you add/subtract...not after

Answer 44

duh

Answer 45

First do the calculation, then round
