Question

What is 12.5% of 150

Answer 1

18.75 because you must multiply the two numbers

Answer 2

one hack is recognizing that
x% of 100 is x
150 is 1.5 times of 100 so
x% of 150=1.5x
therfor
12.5% of 150=1.5*12.5=18.75

anyway

percent means parts out of 100
12.5%=12.5/100=0.125

'of' means multiply
12.5% of 125=0.125*150=18.75

the answer is 18.75
