Step-by-step explanation:
Answer:
The two numbers are 18, and 81.
step-by-step explanation:
If you divide both sides of the ratio by 2 to get 4.5/1, you can then graph that as y=4.5x, finally you just find two numbers that have a difference of 63, which in this case is 18, and 81.
9/12 is the answer, you can't simply then down anymore
132554/100=1325.54
Rounded: 1325.5
I think the answer would be D.
There is 30 students from each grade so we have 30/120 already then add 12 from 9th grade math and add 10 more from 10th grade math, then add 7 from 12th grade math.
30 + 12 + 10 + 7 = 59
59/120 students.
