Answer 1

First of all total student are

$30 - 13$

$17 \: are \: boys$

Now

$17 \times 100 \div 30$

Answer is 56.666 percent

Answer 2

Answer: 56.6%

Step-by-step explanation:

Total number of students = 30

Number of boys in the class = 13

Number of girls in the class = 30- 13 = 17

Now we have to find the percent of girls of the class

Therefore

$\dfrac{\text { Number of girls }}{\text {Total students} }\times 100 \\\\= \dfrac{17}{30} \times 100 = 56.6 \%$

Hence, girls are 56.6% of the class
