10.5 lbs of pure copper in the 200 lb chunk.
A Certain Alloy Contains 5.25% Copper. How Much Copper Is There In A Piece Weighing 200 Pounds?
200 lbs x 5.25% (.0525) = 10.5 lbs
I see that you've clearly found out a way of finishing your homework quickly,not really appreciable way though.But still I can help you with steps and you have to do the calculation alright.I bet you would use the calculator but still remember you will have to learn things for your exams
The question says
5.25 % of 200 pounds is copper
5.25% is 5.25/100 so,
5.25/100 of 200
replace 'of with * sing
that is (5.25/100 )*200
IN BOTH THE ANSWER I'VE GIVEN YOU DO THE CALCULATIONS IN THE BRACKET FIRST TO GET THE RIGHT ANSWER . (I thought you may not know)
