220 - 80 is 140 so 140 x 0.4 is 56 add 80 and 56 to be 136 as the total that day...136/220 is .62 or 62%

I read the question and from what i read i would have to go with this answer. 220 yds is the amt of fence needed to be installed. right? Then she put up 80yds and later she put up 40% of the left over fence which is 140 yrds. 40% of 140 is 56yrds. So your problem would be 80+56=136 which is what you have but your question is what % of the fence did she put up that day and this is how you figure that. 220 X 0.6182 = your answer of 136 yrd.

% of what? or what percent of 136?
You're missing a number.
Say you are looking for 25% of 136.
You put the percentage over 100
25% = 25/100
Reduce the fraction (if possible)
25/100 reduces to 1/4
Now take 136 and multiply it by that fraction (and reduce if possible)
(136)(1/4) = 136/4 = 34

786 makes sense but then so does 567 what r u asking ? now if you want a formula try 100 divided by 136 = .7352941 or the reverse is 136 divided by 100 = 1.36 ( this is the mathematical representation of 136%) which it seems is your ?

220-80=140
140*40%=56
80 yards=first
56 yards = second
136=last
136/220=0.6181=61.81%=62%
