Estimate 78 percent of 20 a. 14 b. 16 c. 19 d. 2

The correct answer is B) 16.

Step-by-step explanation:

In order to figure out the percentage of a number, turn the percentage into a decimal. In this case, the decimal would be 0.78. Then, multiply that number by 20 which should give you 15.6. Since we cant leave the answer like this, we round. 6 is greater than 5 so we round up to 16.
