According to question-
no. of boys +no. of girls =total students
5x + 7x = 36
12x = 36
x = 36/12
x = 3
Therefore,
No. Of boys = 5x =5 * 3 =15
No. Of girls = 7x = 7 * 3 = 21
Answer:
There are 6 more girls than boys in a class of 36 with a boy ratio of 5:7
Step-by-step explanation:
5:7 where 5 + 7 = 12
therefore 12 x 3 = 36
3 x 5 = 15 boys
3 x 7 = 21 girls
21-15 = 6 more girls.
