Answer: 45%
Step-by-step explanation: There's 9 people over the age of 14. And 9 divided by the total number, 20, gives you 0.45. 0.45 multiplied by 100 is 45.
Since Colin can cover a 113 square inch pizza in 1/9 of an hour, he can cover 9 pizzas in an hour. 113 * 9 = 1017 square inches an hour.
Simple division. 269/48=5.60416666667. You probably cannot put decimals, so round to 6.
NB- I used the symbol to represent that the 2 means squared. I hope this helps
