Question

In a school of 528 students, the ratio of boys to girls is 5:6. What is the number of girls in the school?

Answer 1

Answer:

288 girls

Step-by-step explanation:

5:6 = 5/11 boys 6/11 girls

5/11= 0.4545 × 100

= 45.45 % boys

6/11= 0.5454× 100

= 54.54 % girls

Since there are 528 students Then,

528×45.45% = 239.9 but since there is no half human we will round up to 240 boys,

528×54.54%= 287.97=288 girls

Checking: 240 +288= 528

240/288=5/6 or 5:6

Answer 2

Answer:

∴ The number of girls in a school is $288$.

Step-by-step explanation:

• In context with question asked,
• We have to find the number of girls in the school.
• It is given that, total number of students in a school = $528$

           The ratio of boys to girls = $5:6$

• Let, the number of boys be $5x$ and girls be $6x$ in a school.
• According to given data, the required equation becomes,

            $5x+6x=528$

               ∴ $11x=528$

                  ∴ $x=\frac{528}{11}$

                  ∴ $x=48$

• ∴ The number of girls = $6x=6\times 48=288$
• ∴ The number of girls in a school is $288$.
