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.
Hope I helped
