Which expression can be used to find 640% of 700?

OpenStudy (bahrom7893):

Let: 700 be 100% x be 640%, So: 700 - 100% x - 640%

OpenStudy (bahrom7893):

cross multiply: x = (700*640%)/100%

OpenStudy (anonymous):

so 640 divided into 640

OpenStudy (anonymous):

OpenStudy (bahrom7893):

OpenStudy (anonymous):

whatever answer comes up after multiplying 700 into 100

OpenStudy (anonymous):

OpenStudy (bahrom7893):

No look, you don't multiply 700 by 100, you multiply it by 640 and divide by 100
