Question

There are three blue seats for every two green seats in the cafeteria. If there are 80 total seats in the cafeteria, how many are blue?

Answer 1

Answer:

Step-by-step explanation:

Total seats:80

We Known :

No.of blue seats : No. of green seats  = 2 : 3

<let common ratio be x>

now,

No.of blue seats : No. of Total seats  

=No.of blue seats : No. of (green seats+ blue seats) seats  

=3:5

we can say

=>No.of blue seats/  No. of total seats seats   = 3x/5x

=>No.of blue seats=80 x 3/5

=>No.of blue sears=16x3=48
