The easiest way to solve a problem like this is to cross multiply and solve 

The problem gives us a ratio 
2 pounds of granola = 3 pounds of raisins 
which makes a ratio of \frac{2}{3}
The other ratio is 
? pounds of granola = 24 pounds of raisins
which makes a ratio of \frac{x}{24}

To solve, set them equal to each other ...
\frac{2}{3} =  \frac{x}{24}

Now we must cross multiply...
To cross multiply, we multiply 2 and 24 
and we multiply 3 and x 
Now we have an equation to solve!
3x = 48 
To solve and get your final answer, divide...
x = \frac{48}{3}

x = 16
You'll need 16 pounds of granola

Rainbow [258]

Answer:

54
