on his trip across town mark was stopped by a red light at 9 out of 15 intersections at what percent was mark stopped by a red light

60%

Step-by-step explanation:

The first step is to divide 9 by 15 to get the answer in decimal form:

9 / 15 = 0.6000

Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:

0.6000 * 100 = 60.00%

We can prove that the answer is correct by taking 60.00 percent of 15 to get 9:

(15 x 60.00) / 100 = 9

Note that our calculator rounds the answers up to two decimals if necessary. Once again, the answer is as follows:

60.00%

Answer:60%

Step-by-step explanation: divide 9 (red lights) by 15 (intersections) and you get 60% of the time.
