crap, I did something wrong >.<, forget everything I SAID!

anonymous · Answer

If there is 5 grams of a for every 8 grams of b we could create a linear equation.

$$\begin{align}5x + 8x &= 195 \ 13x &= 195 \ x &= \frac{195}{13} \ x &= 15\end{align}$$

At this point you should see how this relationship is established in the equation and using this find the quantity of the greater substance.
