Question

What is 16% of 90?
Please write how you did it

Answer 1

10% of 90 is 9
5% of 90 is 4.5
1% of 90 is 0.9

So.. 9+4.5+0.9= 14.4

Answer 2

you first set up a proportion

16/100 = x/90

then cross multiply 16*90
and 100*x
1440 = 100x
divide each side by 100
1440/100 = 100x/100
100 cancels out on the right side
the answer is
14.4=x
