Determine the number of children who did not like playing football from a survey of 40 children where 25% liked football.
Calculate Number Liking Football
Total children surveyed is 40.
The percentage of children who liked football is 25%.
Number who liked football = $40 \times 25\%
Number who liked football = $40 \times \frac{25}{100}
Number who liked football = $10$ children.
Calculate Number Not Liking Football
Number who did not like football = Total children - Number who liked football
Number not liking football = $40 - 10
Number not liking football = $30$ children.
Therefore, 30 children did not like playing football.
