First off, create a ratio using the information given through the problem. Ratios are used when we need to make a comparison between two or more things. In this case, we are making a comparison between the number of girls in the chorus to the number of boys in the chorus. As there are 5 girls to 3 boys in the chorus, this is a ratio of 5:3 Next, we need to create an equal ratio, which is regarded as either multiplying or dividing each term in the ratio by an equal number. This number cannot be 0, and both numbers of the ratio need to be multiplied by the same number involved. Since we are already given the information and know that there are 24 boys in the class, we need divide 24 by the relevant term of the ratio, which is 3. This will let us know how many times the original term was multiplied to receive the result of total boys. 24 ÷ 3 = 8 The 2nd term of the ratio was multiplied by 8 to receive the result of 24 boys. Multiple the same number by the first term to find out how many girls compare to the number of boys. 5 × 8 = 40 As a result, there are 40 girls and 24 boys in the chorus.
