Answer 2

Answer:

There are 18 girls in the class.

Step-by-step explanation:

Total number of students = number of boys + number of girls = 1

                                             4/7 + number of girls = 1

                                             number of girls = 1 - 4/7 = 3/7

Number of students (n) = 42

Number of girls = 3/7 of n

                          = 3/7 x 42 = 18 girls

Therefore, there are 18 girls in the class.
