How do I subtract this: 68°14' - 8°15'

OpenStudy (unklerhaukus):

\[60°14' - 8°15'\]\[=59°74' - 8°15'\]\[=51°59'\]

OpenStudy (anonymous):

ok wasn't sure I could turn it to 74, lol Thought I would have to keep it at 60

OpenStudy (anonymous):

wait a minute, lol the question is 68°14' minus 8°15'

OpenStudy (radar):

You have to borrow a degree from the 68 which is also 60 minutes so this leaves 67 degree and 74 minutes on top.

Now you can proceed with your subtraction.

OpenStudy (anonymous):

ok then it basic math.

OpenStudy (anonymous):

Thanks.

OpenStudy (radar):

Yes.

OpenStudy (anonymous):

so then the answer is 59°59'

OpenStudy (unklerhaukus):

a degree is 60 minutes \[1°0'=0°60'\]

OpenStudy (radar):

Yes 59 degrees, 59 minutes

OpenStudy (unklerhaukus):

isnt it \[51°59'\]?

OpenStudy (radar):

@UnkleRhakus It was 68 degrees 14 minutes I think you thought it was something else.

OpenStudy (unklerhaukus):

OpenStudy (unklerhaukus):

\[68°14-8°15=59°59'\]
