In my class there are 30 children 18 of them are girls what percent of children in my class are girls

In a class, there are 30 children and 18 of the children are girls. What percent of the class are girls?

The fraction represents the 18 girls in the class out of all the students in the class.

We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 18 and 30 using 6.

18 ÷ 6 = 3

30 ÷ 6 = 5

3 ÷ 5 = 0.6

0.6 × 100 = 60%

Therefore, 60% of the students in the class are girls.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
