The total number of lockers in school is 480.
Given:
There are 180 white lockers in the school.
For every 5 blue lockers, there are 3 white lockers.
To find:
The total number of lockers in school.
Solution:
Number of white lockers in school = 180
Number of blue lockers in school = b
For every 5 blue lockers, there are 3 white lockers.
The ratio of blue lockers to white lockers = 5:3
[tex]\frac{b}{180}=5:3\\\\\frac{b}{180}=\frac{5}{3}\\\\b=\frac{5}{3}\times 180=300[/tex]
Number of blue lockers = 300
Total number of lockers in school :
[tex]= 300 + 180 = 480[/tex]
The total number of lockers in school is 480.
