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
You need to make 225 and 187.5 into a fraction like 187.5/225 then compare that to ?/100 to that you need to figure out what 225 divided by 100 is then divide that answer by 187.5. 225/100=2.25 187.5 divided by 2.25 is 83.3. 100- 83.3= 16.7 percent. You're right if you round it
The answer is z=20 because 25-6 is 19 and rounded that is 20
