Question

60 % of students are girls if the total no. of students is 30 , what is the no. of boys​

Answer 1

Answer:

Step-by-step explanation:

where g = number of girls

g / 30 = 60 / 100

60/100 as 60% and 30 as total classmates

by cross multiplying, 30*60 = 100g

30*60=1800

divide each side by 100 to isolate g

1800=100g

18=g

therefore, g, the number of girls in the class, is 18 girls

so to find the boys subtract 18 from 30

the number of boys is 12
