btw this is dealing with proportions :I

anonymous · Answer

He shouldn't use any sugar.  That stuff is dangerous.  It will harm you.

But if you wanna get diabetes that badly then $$
\frac{2}{36}=\frac{x}{24}
$$

If they are proportional, then the ratios have to be equal, hense the equation.

$$
\frac{2}{36}=\frac{x}{24}\implies 36x = 2\cdot 24\implies x=\frac{48}{36}=\frac  43
