Real-Life Activities

Real-Life Math -- Solution

Total number of children = 100

100 children / 5 groups = 20 children per group

Half of each group are boys and half of each group are girls, so there are 10 girls in each group.

10 girls (in group 5) + 10 girls (in group 4) = 20 girls

20 girls out of 100 children = 20 / 100 or 20 percent

The girls from groups 4 and 5 represent 20 percent of all the children in your experiment.
