Answer :
To find out how many children are wearing jumpers, you can use the proportion of children wearing jumpers to the total number of children.
Given that 2 out of 8 children are wearing jumpers, and there are 40 children in total, you can set up the proportion:
Number of children wearing jumpers / Total number of children = 2/8
Let x represent the number of children wearing jumpers. Then, the proportion becomes:
x / 40 = 2/8
To solve for x, cross multiply:
8x = 2 × 40
8x = 80
Now, divide both sides by 8:
x = 80 / 8
x = 10
So, there are 10 children wearing jumpers in the class.
