Answer 2

Answer:

let total no. of student = s

given :

total no. of boys = 1800

so total no of girls = s - 1800

Step-by-step explanation:

72% of s = 1800

72/100 × s = 1800

s = ( 1800 × 100 ) ÷ 72

s = 180000 ÷ 72

s = 2500

it means total no. of student =2500

total no. of girls = 2500 - 1800 = 700 Answer

and the ratio is = 700/1800

= 7/18 Answer
