4/3/8 what is the unit rate

Question

sally is bundling magazines to recycle. She notices that 4 magazines weigh 3/8 pound in all , and that the magazines all weigh the same amount. what is the unit rate for pounds per magazines.

Answer 1

4 magazines weigh 3/8 pound. Each magazine weighs (1/4)(3/8)=3/32 lb.

1lb=16oz, so each magazine weighs (3/32)16=3/2=1.5oz.

So the unit weight is 3/32lb per magazine (or 1.5oz per magazine).
