Answer:
21 students earn the reward
Explanation:
15% is equivalent to the fraction 3/20 so, you must divide 140 by 20 then multiply by 3 to get the final answer of 21 students.
15% = 3/20
140 divided by 20 = 70
70 x 3 = 210
210 divided by 10 = 21
In conclusion, your answer would be that 21 students get the Presidential Physical Fitness Award.
Have a great rest of your day
