Question

Write and solve a proportion to answer the question: what number is 45% of 60?

Answer 1

proportion

what is 45% of 60
what=45% of 60
60=100%
45%=what
60/100=what/45
3/5=what/45
multiply both sides by 45
27=what

the number is 27

Answer 2

60 *.45 = $60 * \frac{45}{100} = \frac{5*12*5*9}{2*5*5*2} = \frac{6*9}{2} = \frac{54}{2} = 27$
