Answer:
Step-by-step explanation:
first of all the question is wrong 1 kilogram = 2.2046 pounds. and 1 pound = 0.4536kilogram.
if we want to convert 112lb into kilogram. we multiply it by 0.4536.
ie 112lb = 112x0.4536kg = 50.8032kg
to convert lb to kg you do this; lb x 0.4536
to convert kg to lb you do this; kg x 2.2046
8*5=40
2/5= 16/40
3/8= 15/40
1 16/40-15/40= 1 1/40
1 1/40 is the final answer.
I hope this helps!
