Question

Everyone in Andy’s class has to do a science project. Out of the 20 students, 80% have completed their project. How many students still need to finish their projects (got 4 students)

Answer 1

Right.

Answer 2

Ms. Sue is wrong. You are finding 80% of 20. Multiply 80 times 20, and get an answer of 1600.

Then, multiply 1600 by 100, and get an answer of 16. You are not simplifying.

Or, Multiply 8x2 and get 16, either way.

Answer 3

No Ms. Sue is correct because you have to multiply 20 by .80 and get 16
But then you have to subtract 16 by the original number so
20 - 16 = 4
Answer is 4 students need to finish

HOPED this helps

Answer 4

Ms. Sue is correct.

Answer 5

I trust Ms. Sue, and besides, I come looking for help, or giving help. Not answers! Sometimes I like a explanation. Maybe I should go to a different site, one that does not cheat.

Answer 6

thanks kkb

Answer 7

swords jeez dude stop being so mean you shouldn't have a problem with it at least you have the answer

Answer 8

for real

Answer 9

I am correct

Answer 10

Ms. Sue is right because the question asked for how many students STILL need to complete their projects, not how many already completed it.

Answer 11

just divide

Answer 12

Yes, you can also divide the original number of students by 5 to find the number of students who have not completed their projects.

20 divided by 5 = 4

So there are 4 students who still need to finish their projects.

Answer 13

80 divided by 20

Answer 14

The result of 80 divided by 20 is 4.
