4/5x-2>3/5x (3/10*2=3/5)
-2>-1/5x (subtract the 4/5x)

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.
