there were 25pupils in a class. they had 135 books altogether. two-fifth of the pupils were girls.they had the same number of books each. the remaining pupils were boys.each boy had one-third as many as each girl.how many books did each girl have?
girls = 2/5 * 25 = 10
boys = 25-10 = 15
If each girl had g books, each boy had g/3 book
total books: 10g + 15g/3 = 135
15g = 135
g = 9
so each girl had 9 books, each boy had 3.
10*9 + 15*3 = 90 + 45 = 135 books in all
Please can you give me the exactly answer please
Girls= 2/5*25= 10
Boys = 3/5*25= 15
All books= 135 books
135÷3= 45÷15= 3*3
= 9 books
How to solve that my question findmissing term in math I hope my question is delever toyou

Please can you give me exactly answer please
To find out how many books each girl had, we need to follow the given information step by step.
1. The class has 25 pupils. We are told that two-fifths of the pupils are girls. To find how many girls there are, we calculate:
25 pupils x (2/5) = 10 girls
2. We know that the remaining pupils are boys. To find the number of boys, we subtract the number of girls from the total number of pupils:
25 pupils - 10 girls = 15 boys
3. Now we need to determine how many books each girl has. We are told that the girls and boys have the same number of books. Let's assume that each girl has 'g' books.
4. Since each boy has one-third as many books as each girl, we can calculate how many books each boy has:
Each boy has (1/3) x 'g' books
5. We know that the total number of books in the class is 135. We can use this information to set up an equation to solve for 'g':
10 girls x 'g' books + 15 boys x (1/3) x 'g' books = 135 books
Simplifying the equation, we get:
10g + (15/3)g = 135
10g + 5g = 135
15g = 135
g = 135 / 15
g = 9
Therefore, each girl in the class has 9 books.
