have left?
A.33/56
B.1/5
C.5/8
D.23/40

Answer 1

Do you have any ideas of the answer or how to find the answer?

Answer 2

@scienceteen8

Answer 3

no

Answer 4

Ok, well, the first step is to find the common denominator of both fractions
Do you know how to do that?

Answer 5

multiply the numerator and denominator?

Answer 6

That would work in this problem
But keep in mind sometimes there is a lower common denominator
Anyways
You would multiply both denominators to find the common denominator

Answer 7

ok

Answer 8

is the answer a

Answer 9

Why do you believe the answer is A?

Answer 10

yup it's a

Answer 11

(7/8)*(7/7)=(49/56)
(2/7)*(8/8)= (16/56)
So (49/56)-(16/56)= 33/56

Answer 12

@raventayler13
You would be absolutely correct
however, I was trying to get @scienceteen8 to complete the problem so that they know how to do it themselves

Answer 13

Hence, they would learn how to do it on their own

Answer 14

i did complete it lol i said it was a befor @raventayler13 completed it lol

Answer 15

sorry @JackofallTradez i was just trying to help

Answer 16

And I was asking you why you thought it was A
I didn't see any of your work, so I couldn't know if you had solved it or not

Answer 17

@raventayler13
I know, it's ok
I was sort of tempted of just working out the problem and leaving the work to show my answer because this was such an easy problem for me

Answer 18

oh ok i thought it as a because 7*8 is 56 and no i did not look at what @raventayler13 said bc i was trying to see if i got it right

Answer 19

@scienceteen8
Ah, that's why I thought you asked if A was the answer
You can't always find the common denominator and assume that the answer with the common denominator is the correct answer, because sometimes the fraction simplifies

Answer 20

However, in this problem, it would be correct

Answer 21

ok thank you @JackofallTradez

Answer 22
