OpenStudy (anonymous):

help

OpenStudy (amistre64):

without any context its hard to tell, but if your trying to turn it into an improper fraction ... then no.

OpenStudy (anonymous):

@amistre64 Find the reciprocal of the number. Multiply to check your answer. this is the question

OpenStudy (amistre64):

hmm, then we have to process 2 3/4 into an improper fraction, then flip it keep in mine that \[2\frac34=2+\frac34\] so what is: \(2+\frac34\) equal to?

OpenStudy (anonymous):

so the answer is B

OpenStudy (anonymous):

@amistre64

OpenStudy (amistre64):

the answer is at the end, this is only 1 step of 2

OpenStudy (amistre64):

11/4 is equal to 2 3/4 now we can get the reciprocal, flip it.

OpenStudy (anonymous):

Oh so A

OpenStudy (amistre64):

are we looking at the same A ? it may be better to tell me what 11/4 looks like when we flip it over

OpenStudy (anonymous):

4/11

OpenStudy (anonymous):

C

OpenStudy (amistre64):

then lets choose the one that has 4/11 ...

OpenStudy (amistre64):

i agree with C :)

OpenStudy (anonymous):

can u help with another plz

OpenStudy (amistre64):

maybe ...

OpenStudy (anonymous):

ok great

OpenStudy (anonymous):

one last question

OpenStudy (anonymous):

Which number is the reciprocal of 1/5 A.-5 B.-1/5 C.0 D.5

OpenStudy (anonymous):

i think it is B. @amistre64

OpenStudy (amistre64):

the reciprocal of x/y is y/x the reciprocal of x/y is NOT -x/y its not B

OpenStudy (amistre64):

so, if we take 1/5 what does it look like when we flip it over?

OpenStudy (anonymous):

D

OpenStudy (amistre64):

yes, 5/1 = 5 so D is it
