The easiest way is to make sure you have the same amount for each of the questions.

For example if you want to compare C and D you would multiply C by 2 and D by 3.

If you want to compare them all at once you would need to cross-multiply with all 4 of them.

If you want to get 150g of C you would need to buy 2 packages of C, while if you want to get 150g of D you'd need 3 packages.
