This indicats that 440 students make up 55% of the 6th grade population. We can write this as
55/440.
We also know that 'x' total students make up 100% of the 6th-grade population, so we can write this as
100/x.
55/440 must be equal to 100/x. When cross multiplied, it becomes 50x=44000. If we divided each side by 50, we'll find that x=880. Therefore, there are 800 6th graders
440 rounds up to 450,450+450=900-the 10 we rounded so 890-440 is 450 which is half so we need to add 440 to 550 to get 990 and we half 990 to get 495 and that is your answer i think im very sorry if this is wrong btw a sixth grader did this please find out a way to reply to my comment or something like that to tell me if i am right.
