Answer:
we express the ratio of pencil to eraser and multiply it by the number of the number of pencils and erasers. 4/5 * x=20 , so x=25, then it implies that there are 5 erasers.
Step-by-step explanation:
range=highest -lowest
=9-1
=8
mode=greatest frequency
=9
(1/3) / (2/7) = x / 1
cross multiply
(2/7)(x) = (1/3)(1)
2/7x = 1/3
x = 1/3 * 7/2
x = 7/6 = 1 1/6 liters
