Answer
Amount of other nuts = 216
Work Step by Step
(Note: Ratio x to y is same as x:y and $\frac{x}{y}$)
Ratio of peanuts to other nuts is 3 to 2 or 3:2
Now, if there are 324 peanuts, and say 'x' number of other nuts,
then ratio is 324 to x.
But 324 to x = 3 to 2.
Thus $\frac{324}{x}$ = $\frac{3}{2}$
Cross multiplying,
3(x) = 324(2) = 648
Thus x = $\frac{648}{3}$ = 216
Thus amount of other nuts = 216
