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.
U're goal is to get k alone.
So divide both sides by 9/10.
3/2 divided by 9/10 is 5/3
