Practice makes perfect

Let's take a look at the given ratio.

wheat &rice &oats 2 : & 4 : &1 From this ratio we can deduct that we have two times more rice than wheat in this breakfast cereal. Therefore, if there are 110 pounds of wheat, then the manufacturer needs to use two times more pounds of rice. 2* 110=220 This means that the manufacturer needs to use 220 pounds of rice, so the answer G is correct.
