my recommendation is to convert each fraction answer choice to a decimal number
jimthompson5910 (jim_thompson5910):
that way you can compare
OpenStudy (jhannybean):
so you have 0.85 which is \[\frac{ 17 }{ 20 }\] and sowhen you compute \[\frac{ 4 }{ 5 }\] you get 0.80
jimthompson5910 (jim_thompson5910):
using a calculator, 22/25 = 0.88
since 0.85 < 0.88, this is why C is wrong
OpenStudy (anonymous):
I meant "D" ehehe

Ask yourself "what number do I have to multiply the donominator by so it gives 100."
100 then multiply that numerator by that same number. Its the numerator that gives the answer
4/ 5 X 20 = 80/100 then multiply that denominator by that's a number
so itd D
