Answer 1

Math homework questions.
Easy, just do them.
Percent means over 100 or (out of 100)

o*If you type 60, he types 80 WPM, the ratio is 3 to 4
He types 80/60 .. 4/3 .. 133/100 .. or 133% of your speed,
you type 60/80 ..3/4 .. 75/100 .. or 75% of his.

* 5.25% (per hundred, remember?)
200 pounds so 200 x 5.25/100 .. or .0525 = 10.5 lb.s of copper

*34.55% (per hundred{100} remember?)
so 34.55 x 1/100 = .3455

Your english needs work too.
