Question

In a class of 30 students,1/10 are girls. Find the number of boys and girls in the class

Answer 1

• NO. OF STUDENTS IN THE CLASS = 30
• FRACTION OF GIRLS = 1 /10

TO FIND NO. OF GIRLS WE NEED TO MULTIPLY 1 /10 WITH 30

$\frac{1}{10} \: \: \times \: \: 30 \\ \\ 1 \times 30 \: = 30 \\ \\ \frac{30}{10 } \: \: \: 30 \: divided \: by \: 10 \: is \: 3 \:$

• SO NO. OF GIRLS = 3
• NOW NO. OF BOYS = 30 - 3 = 27
• SO NO. OF GIRLS = 3
• NO. OF BOYS = 27

Answer 2

Answer:

If in a class of 30 students,1/10 are girls, then the number of boys is 27 and girls is 3.

Step-by-step explanation:

Total students in the class= 30 students

1/10 of 30 are girls

So the number of girls = $=\frac{1}{10} \times 30= 3$ girls

And the number of boys  = 30 - 3 = 27 boys

Hence, the number of boys is 27 and girls is 3 in the class.
