In the class of 28 students, 10 students are girls. In the simplest form, what is the ratio of females to males?

Answer: 9:5

Step-by-step explanation:

If there are a total of 28 students in class, 10 are girls

Step 1: find the number of boys;

Number of boys = Total number of students - number of girls

= 28 - 10 = 18

Number of boys = 18

Step 2: the ratio of boys to girls can therefore be written as 18:10 or 18/10 in fraction form.

To put in the simplest form, we divide by the greatest common factor as both 18 and 10 are divisible by 2, so the simplest form is 9:5 or 9/5

1£/10 = 9/5, in other words, there are 9 boys for every 5 girls in the class.
