so just take percents of 140 that are given and see which one works. or you could do it as a fraction. 68.60/140

Could you walk me through im lost

take 68.6/140 and reduce it to smallest form. think about it. what is half of 140 or half of 14
OpenStudy (anonymous):
70
OpenStudy (anonymous):
ok. so since 50% is 1/2 you know that its either 45% or 50% is closest right? just have to find which one.
so reduce 68.6/140 and you should get 4X% then whatever you get for your second digit will determine which is closer.
