Sagot :
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
=> 5/7x = 40.5lbs
=> 40 1/2 * 7/5 = x
=> 81/2 * 7/5 = x
=> 567/10 = x
=> 56.7 lbs = x

=> 56.7 lbs
first convert 5/7 into a decimal
5 divided by 7= .71
and 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= 57.04
That's how I got my answer...
