Question

In a class 40 students,3/10 of the students are boys. What fraction of the students are girl? Also find the number of boys and girls in the class

Answer 1

Answer:

The fraction of the students who are girls is 7/10. There are 12 boys and 28 girls.

Step-by-step explanation:

1 = 3/10 boys + x girls

1 - 3/10 = 7/10 girls;

In a class of 40 students, 30% are boys and 70% are girls.

To get the number of boys, 40 students * 30% = 12 boys

To get the number of girls, 40 students * 70% = 28 girls
