Hi! I can help :)

OpenStudy (anonymous):

So, if he missed 15/30 throws, how many did he make?

OpenStudy (anonymous):

35* sorry

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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 :) )

Vocaloid (vocaloid):

yeah looks good to me, gj
