Answer:
800
Explanation:
If the ratio of students to laptops in the school is 3:2 and there are 1,200 students, you can use the ratio to find the number of laptops.
Let x represent the number of laptops.
The ratio of students to laptops is 3:2
3:2, which means for every 3 students, there are 2 laptops.
Now, set up a proportion to find the number of laptops:
Number of students/Number of laptops=3/2
Given there are 1,200 students:
1,200/x=3/2
To solve for x, cross multiply:
1200*2=2400
3*x=3x
that will result in 3x=2400
Now, solve for
x (number of laptops)
3x=2400
divide both sides by 3
x=800
Therefore, according to the ratio, if there are 1,200 students in the school, there would be 800 laptops.
