On the first math exam, 16 students received an a grade. on the second math exam, 12 students received an a grade. what percentage decrease is that?

25%

Step-by-step explanation:

So, first, you need to subtract 16 by 12, 16-12, which should be 4. after that step, you need to divide 4 by the actual number of students. that should be 16 students. so now, you should get .25, but then to get the percentage, you need to move the decimal point two spaces to the right, or multiply it by 100. then you get 25%.

PSST!! put this in your notes for math, if you want for tests!

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
