Question

THERE ARE 3 BAGS OF APPLES WEIGHING A TOTAL OF 22 1/2 POUNDS. TWO OF THE BAGS WEIGH 6 3/8 POUNDS AND 3 1/4 POUNDS. HOW MUCH DOES THE THIRD BAG WEIGH?

Answer 1

22 1/2= 6 3/8+ 3 1/4+ x
22 1/2= 6+3(3/8+1/4)+x
22 1/2= 9 (3/8+2/8) +x
22 1/2= 9 5/8 +x
22 1/2 -9 5/8 =x
22-9(1/2-5/8)=x
13(4/8-5/8)=x
13 (-1/8)=x
12 7/8
