OpenStudy (aussiebabe23):

What did you get when you subtracted

OpenStudy (aphmau64):

84.96

OpenStudy (aussiebabe23):

ok the rule for rounding is 5 or more round up and 4 or less you round down. so since the last number is a 6....

OpenStudy (aphmau64):

thank you

OpenStudy (aussiebabe23):

what answer did you get?

OpenStudy (aphmau64):

84.90

OpenStudy (aussiebabe23):

you rounded up the 6 so you have to add one more to the number before it. add one to the 9

OpenStudy (aphmau64):

ok

OpenStudy (aussiebabe23):

so what do you get now

OpenStudy (aphmau64):

84.9

OpenStudy (aussiebabe23):

that's not the right answer

OpenStudy (aphmau64):

well got it right it said

OpenStudy (aussiebabe23):

When you round the 6 up you have to add one to the 9 and after 9 comes 10 which means you have to add one to the next number.

OpenStudy (aussiebabe23):

you better check that because that's definitely wrong!
