3/5 of the children makes 48 girls. 1/5 would be 48/5 = 16. Thus total number of children would be 16x5=80

80 children makes 4/7 of total number of people. 1/7 would be 80/4 = 20. Thus, total number of people would be 20x7=140.

Hope this clarifies.

Pl note that 3 unit of girls represent 48 sof for one unit it should be 48/3 = 16. Thus the no of children would be 16x 5 = 80
