ANSWER
========
Ratio of 8th graders to 7th graders = 3 : 2
Let the number of graders be 3x and 2x
Number of 8th graders = 18
So , 3x = 18
x = 18/3 = 6
Number of 7th graders = 2 × 6 = 12
Ratio of 6th graders to 7th graders = 5 : 4
Let the number of graders be 5a and 4a
Number of 7th graders = 12
So , 4a = 12
a = 12/4 = 3
Number of 6th graders = 5×3 = 15 ANS

Answer:
The answer is 13 m/1 m = <u>1300 cm</u>/100 cm.
Step-by-step explanation:
Given:
13m/1m = ?/100cm.
Now, to find the answer in the place of <u>? </u> .
13m/1m = ?/100cm.
As, <em><u>1(m) metre = 100(cm) centimetre.</u></em>
So, by multiplying 13 m with 100 we get:

Thus, 13 m/1 m = 1300 cm/100 cm.
Therefore, the answer is 13 m/1 m = 1300 cm/100 cm.
