A certain alloy contains 5.25% copper. How much copper is there I a piece weighing 200 pounds?
kykrilka [37]
Find 5.25% of 200
remember
1% of 100=1
therefor
1% of 200=2
just remove the decimal and double it (for this special case of finding percent of 200)

5.25% of 200=5.25 times 2=10.5
answer is 10.5 pounds of copper
(the legit way is 0.0525 times 200=10.5 pound)


10.5lb is answer
