W = weight of the bag of bricks
W + 1/4 W = 25 pounds
5/4 W = 25 pounds
5W = 100 pounds
W = 20 pounds

Let W be the weight. We're told that the weight plus a quarter of it is 25 pounds. So W + (1/4)W = 25. Solve this for W.

Let bag of bricks weight be W.
Youve just told us that 1.25 x W = 25.
Therefore W = 25 divided by 1.25
So W = 20 pounds, according to my calculations.
20 pounds should be the answer.

if 25 pounds is the bags weight plus 1/4 its weight, that means it is
1/4+1/4+1/4+1/4+1/4 which is 5/4
now we divide.
25 divided by 5/4 or 1.25
and the answer is 20

Let W be the weight of the bricks
w+1/4W=25
5/4 W= 25
5W=100
W=20 pounds (don't forget the units!)

let 1/4 be a p so you have 4p as the weight of the object and another p as the 1/4 you're adding.
4p+p=25 so p=5 so if you take 5*4 you get 20 lbs.
