if the weight of a package is multiplied by 5/7 the result is 40.5 pounds. Find the weight of the package.

ok let x represent the weight of the package. So the package multiplied by 5/7 is 5/7x. => 5/7x = 40.5lbs => 40 1/2 * 7/5 = x => 81/2 * 7/5 = x => 567/10 = x => 56.7 lbs = x OR let 1 equal the weight of the package 5/7 = 40.5 lbs 1 = x => 40.5 divided by 5/7 => 81/2 * 7/5 => 567/10 => 56.7 lbs

first convert 5/7 into a decimal 5 divided by 7= .71and if the total weight was multiplied by .71 (same as 5/7) to get the original weight you must do the opposite operation which is division. 40.5 divided by .71= 57.04That's how I got my answer...
