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.

though don't really understand the question
Step-by-step explanation:
i would say
y= nx
y=180
so 180=n5
divide both sides by 5
180/5= 36
the answer is D= 36
