Question

In a class of 60 students,the ratio of boys to girls is 2:3.The number of girls is

Answer 1

Answer:

No. of girls= 36 girls

Step-by-step explanation:

No. of students - 60

Total parts = 2 + 3 = 5

No. of boys = 2/5 X60

= 2/1 X 12

= 2 X 12

= 24 = 24 boys

No. of girls = 3/5 X60

= 3/1 X 12

= 3 X 12

= 36

∴ No. of boys = 24          , No. of girls - 36

Answer 2

Answer:

• let the number of boys be 2x
• and a number of girls be 3x
• total number of students in the class 60

number of boys + number of girls = 60 students

$2x+3x =60$

$5x=60$

$x = \frac{60}{5}$

$x = 12$

now that we have the value of x let's find the value of boys and girls in a class.

boys = 2x

= 2×1

= 24

Girls = 3x

= 3×12

= 36

therefore number of girls is 36
