Question

9 over 4- 8 over 12=?

Answer 1

is that \[\frac{9}{4} - \frac{8}{12}\]?

Answer 2

reduce first

Answer 3

right @whpalmer4 ??

Answer 4

yes to palmer

Answer 5

No, can't reduce...

Answer 6

can't reduce in a useful fashion, that is.

Answer 7

need to make a common denominator. 12 is a multiple of 4, so we can use 12 as the common denominator. What do we need to do to make the denominator of \(\dfrac{9}{4}\) be \(12\)?

Answer 8

I know there is 27-8 over 12

Answer 9

Yes, \[\frac{9}{4}*\frac{3}{3}-\frac{8}{12} = \frac{27}{12} - \frac{8}{12} = \frac{27-8}{12} = \]

Answer 10

19 over 12

Answer 11

that's correct!

Answer 12

Is that the answer tho?

Answer 13

Yes, unless the problem asks that it be made a proper fraction. You can't reduce 19/12, as 19 is a prime number, and so has no factors other than 1 and 19.

Answer 14

actually this is the correct meaning of the question...

Answer 15

It was 19/12

Answer 16

alternative answer would be \[1\frac{7}{12}\]

Answer 17

no answer would be -27

Answer 20

@chetan552 she knows what the problem looks like on her screen or in the book. yes, what you provided was the correct interpretation of what she typed, but she didn't type what she meant.

Answer 21

She even told us that the correct answer was 19/12...

Answer 22

Part of the joy of OpenStudy is that you have to decipher what the problem really is from what may be an imperfectly transmitted description :-)
