Okie, so you have an whole number subtracted by a fraction of a number. The way to approach this problem is to convert whole number to the LCD (least common denominator) of the fraction. In this case it would be 6.
6 would be 36/6 (same number just different form)
now just subtract the numerators over the denominator
(36-1)/6 = 35 / 6 is your answer as an improper fraction. As a mixed number, it would be 5 5/6.
I hope this helps :-)

-4.8n = 13
====================
Multiply Both Sides By 10:
-4.8n * 10 = 13 * 10
Refine:
-48n = 30
Divide Both Sides By -48:

I am pretty sure the quartile is just the third number in a data set so it would 39? I do not recommend using this I am only 14 after all <span />
In interval notation it should be [6, ∞)
Answer:
No.
Step-by-step explanation:
Change it so that both fractions would have the same denominator. Note that what you do to the denominator, you must also do to the numerator.
Multiply 3 to both the numerator & denominator of 8/20
(8/20)(3/3) = 24/60
24/60 ≠ 25/60 ∴ these 2 fractions are not proportional.
