Ninety percent of the students or 540 students attended a school assembly. how many students are there at the school

if 540 is 90% or 0.9 then 0.1 or 10% is 1/9 of 540.

540/9 is 1/9 of 540, and 10% of the school's population. that makes 60

so 540 + 60 = 100% of the school assembly.

600 students

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

1/2*qr*rs
