how is this solved ? 128.4 is what percent of 319?

OpenStudy (jim766):

128.4 is what % of 319 128 = x% * 319

OpenStudy (jim766):

solve for x

OpenStudy (anonymous):

is/of = %/100 I think

OpenStudy (anonymous):

i was attempting to place the x over /100 . it was not working out. thanks. i will try this way.

OpenStudy (jim766):

well it is 128 = (x/100) * 319

OpenStudy (jim766):

divide both sides by 319, then multiply by 100

OpenStudy (jim766):

then add a % sign to answer

OpenStudy (jim766):

what did you get?

OpenStudy (anonymous):

ok, trying it that way then.

OpenStudy (anonymous):

i think i have the answer, but i want to see what you get first.

OpenStudy (anonymous):

the last method yielded the correct answer . thanks

OpenStudy (anonymous):

40.25%

OpenStudy (anonymous):

Yes, similar to what I got

OpenStudy (anonymous):

40.25... I remember

OpenStudy (anonymous):

I think the easiest way to do it is use a calculator and put in 128.4 / 319

OpenStudy (anonymous):

But you may have to show the work every time

OpenStudy (anonymous):

how about this one, to see if i have this sorted out correctly ? 64% 0f 325 is what ? (64/100) * 325 = x

OpenStudy (jim766):

right , .64(325) =

OpenStudy (anonymous):

Yes, I did both strategies and got the same answer

OpenStudy (anonymous):

thanks Justine and Jim
