um 20/30?
OpenStudy (anonymous):
20/35 (he made 35 total)
OpenStudy (anonymous):
oh yea sorry i meant 20/35 lol
OpenStudy (anonymous):
So, we need to basically do the opposite of simplifying, we need to make it so both fractions are equal. 35 x __ = 100?
OpenStudy (anonymous):
Both denominators* Sorry again XD

its almost 3 times....
OpenStudy (anonymous):
Mhm. So, keep the decimal (because its a pain to write out, i would use a calculator.) and times it by 20.
OpenStudy (anonymous):
about 57.143
OpenStudy (anonymous):
Mhm :) and the closest answer is 55. which, makes sense because 20 is a little over half of 35. @Mahmood786123 would you agree?
OpenStudy (anonymous):
or @Vocaloid @Voltage Do either of you agree? (Just want to double check that its right :) )
