Choose the missing number to make equivalent fractions.

OpenStudy (anonymous):

@gorv

OpenStudy (anonymous):

I WILL GIVE MEDAL

OpenStudy (vianne):

7/10 Since 28 divided by 7 = 4. If you do 40 divided by 4 then it'd equal to 10.

OpenStudy (anonymous):

Can you help me with another 1 @Vianne

OpenStudy (vianne):

Sure

OpenStudy (anonymous):

Which number can replace the variable to make these fractions equivalent?

OpenStudy (anonymous):

n/9=56/63

OpenStudy (vianne):

Well you know that 63 divided by 9 = 7.. So if you divide 56 by 7 what do you get?

OpenStudy (anonymous):

8

OpenStudy (vianne):

All they want is just for you to simplify the answer. 8 is correct.

OpenStudy (anonymous):

Which is a correct comparison of the fractions? 15/18 and 25/30

OpenStudy (anonymous):

@Vianne

OpenStudy (anonymous):

srry its jut really hard

OpenStudy (vianne):

Hmm.. Do you have answer choices? Since I'm kinda confused on that question..

OpenStudy (vianne):

E.g, A,B,C,D

OpenStudy (anonymous):

A.15/18<25/30 B.15/18>25/30 C.15/18=25/30

OpenStudy (vianne):

Thanks. It's C.. Since if you did 30 divided by 18 then it'd be 1.66666666667 I didn't count the amount of 6's... But if you also do 25 divided by 15 then you get the same answer..

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

Which pair of fractions shows and correctly converted with their least common denominator?

OpenStudy (anonymous):

5/6 3/8

OpenStudy (anonymous):

@Vianne

OpenStudy (vianne):

Do you have answer choices for them as well? So I don't get the wrong answer for you..

OpenStudy (vianne):

Because the only denominator I can think of is 14 as their least common denominator.. :/

OpenStudy (anonymous):

A.5/48 and 3/48 B.40/48 and 18/48 C.5/24 and 3/24 D.20/24 and 9/24

OpenStudy (anonymous):

@Vianne

OpenStudy (vianne):

Thanks, it's D

OpenStudy (anonymous):

Thank you

OpenStudy (vianne):

'cause 8 x 3 = 24, 6 x 4 = 24 5 x 4 = 20 = 20/24 3 x 3 = 9 = 9/24

OpenStudy (anonymous):
