Method: 27 ÷ 60 × 100 = 45%
12% of 890 is 106.8 Method: (12 × 890) ÷ 100 = 106.8
well you use the proportions method and do 4.6/100=x/5 and you can multiply 5x20 to get 100,so to get the answer, you divide 4.6 by 20 which is .23 so 4.6 percent of 5 is .23
20% of 120 is 24 ************************ Method: 20 ÷ 100 × 120 = 24
One method is to divide 150 by 100 and then multiply the answer by 20, you will find the answer is 30
