Question

Terry has an ant farm in her room. She randomly selects 24 ants to study and notices that 10 of them are red. If there are 186 ants in her ant farm, how many of them are red?

Answer 1

78 ants are red

Explanation:

To solve this find out that percentage of the ants that are red. To do this divide 10 by 24. This gives you 0.42 when rounded to the nearest hundredth. 0.42 is also 42%. Take the total 186 ants and multiply it by 0.42. This gives you 78.12. Since you can't have part an ant round it down to 78.
