Sagot :
Answer:
8
Step-by-step explanation:
let the ratio constant be 'x'
=> 2x:3x
sum = 2x + 3x = 5x
Total number of boys
=>(2x/5x)20 = 8
Question -:
The ratio of boys and girls in a classroom is 2 : 3 respectively. If the total number of children is 20. How many boys are there in the class ?
Explanation -:
In this question we are provided with the ratio of boys isto girls that is 2 : 3 it is also given that total number of children are 20. We are asked to calculate number of boys.
[tex] \green{ \small \pmb{\tt{ First \: we \: will \: form \: an \: equation }}}[/tex]
Let us assume the number of girls as 3x and number of boys as 2x.
Total number of children = 20
3x + 2x = 20
[tex] \orange{\small \pmb{\tt{ Now \: we \: will \: solve \: this \: equation }}}[/tex]
[tex] \small\frak{ 3x + 2x = 20}[/tex]
[tex] \small\frak{ 5x = 20}[/tex]
[tex] \small\frak{ x = \dfrac{20}{5} = 4}[/tex]
[tex] \small \underline{ \boxed{\pmb{x = 4} }} \large \: \star[/tex]
Boys = 2 × 4 = 8
Girls = 3 × 4 = 12
- Hence 8 boys and 12 girls are there in the classroom.
