Question

In class of 30 children, 60%
can swim. How many children
cannot swim?

Answer 1

Answer: 12 children

If 60% can swim, then that means 40% do not swim.

40% = 4/10 = 2/5

2/5 * 30 children = 12 children.

100% - 60% = 40%

40% cannot swim.

40% can become 0.4.

30 children * 0.4 = 12 children cannot swim
