Hint 18 = 15 + 3

Answer 2

@pgpilot326 thats a. and I need one more...

Answer 3

\[\frac{ 18 }{15 }=\frac{ 15+3 }{ 15 }=\frac{ 15 }{ 15 }+\frac{ 3 }{ 15 }=?\]

Answer 4

@pgpilot326 a and d

Answer 5

Well you have:
\[\frac{ 18 }{ 15 } = \frac{ 15 }{ 15 }+\frac{ 3 }{ 15 }\]\[1+\frac{ 3 }{ 15 }=\frac{ 15 }{ 15 }+\frac{ 3 }{ 15 }\]\[3+\frac{ 1 }{ 15 }=\frac{ 3*15 }{ 15 }+\frac{ 1 }{ 15 }\]\[\frac{ 13 }{ 15 }=\frac{ 13 }{ 15 }\]
which do you think are the same?

Answer 6

I think its...

\[\frac{ 18 }{ 15 } and \frac{ 3 }{ 15 }\]

Answer 7

Answer 8

Okay 3/15 is not one of your options

18/15 is correct, but look at the sums I did above, which of the sums give you 18/15?

Answer 9

@sarahusher there was a typo with the copy and paste and a wasnt 18/15 it was 1 1/5 so I fixed it you can look at the problem again

Answer 10

@sarahusher hello?

Answer 11

Okay :) no problem, so it's:

A) one and one over five \[1+\frac{ 1 }{ 5 }=\frac{ 5 }{ 5 }+\frac{ 1 }{ 5 }=\frac{ 6 }{ 5 }\]
B) one and three over fifteen \[1+\frac{ 3 }{ 15 }=\frac{ 15 }{ 15 }+\frac{ 3 }{ 15 }=\frac{ 18 }{ 15 }=\frac{ 6 }{ 5 }\]
C) three and one over fifteen \[3+\frac{ 1 }{ 15 }=\frac{ 3*15 }{ 15 }+\frac{ 1 }{ 15} =\frac{ 46 }{ 15 } \]
D) thirteen over fifteen \[\frac{ 13 }{ 15 }\]

Looking at those, which two are the same?
