Answer 2

⛦ Given :

• 45 % of the students are boys.
• The total number of students = 880

⛦ To find :-

• The number of girls in the school.

⛦ Solution :-

First we will try to find the number of boys in the school.

So,

${\sf{\text{Number of boys= 45\%of 880}}}$

${\sf{\text{Number of boys=}}}\sf\dfrac{45}{100}\times{880}$

${\sf{\text{Number of boys=}}}\sf\dfrac{\cancel{45}^9}{\cancel{10}_2\cancel{0}}\times{88\cancel{0}}$

${\sf{\text{Number of boys=}}}\sf\dfrac{9}{\cancel{2}_1}\times{\cancel{88}^{44}}$

${\sf{\text{Number of boys=}}}\sf{9\times44}$

${\underline{\boxed{\sf{\text{\pink{Number of boys=396}}}}}}$

Now,

The number of girls in the school is easy to find.

No. of girls = Total students - No. of boys

${\sf{\text{Number of girls=880-396}}}$

${\underline{\boxed{\sf{\text{\blue{Number of girls=484}}}}}}$
