If the arithmetic mean of m, n, and o is 4 m and m is not equal to 0, what is the ratio of m to the sum of n and o ?

Explanation	Calculations	Help
$We translate "arithmetic mean of m, n, and o is 4m" into an equation.$	$\frac{m + n + o}{3} = 4 m$
$We multiply both sides by 3 and then subtract m to isolate n + o.$	$m + n + o = 12 m n + o = 12 m - m n + o = 11 m$	Theory & Tactics Method Card EQUA1-B Click to view full details
$We express the ratio of m to n + o and simplify the fraction.$	$\frac{m}{n + o} = \frac{m}{11 m} = \frac{m}{m \times 11} = \frac{1}{11} 1 : 11$	Theory & Tactics Method Card FDPR2-A Click to view full details
