Answer 2

Answer:

5%

Step-by-step explanation:

It's a badly worded question in my opinion, but i re-read it and realised 3 bags of oats =300%, add 80% more of oats making it 380% of oats. The other 20 % is wheat bran.

As a ratio, it is 20:380, the total is 400 and we need to simplify this to make it 100 so we can see it as a percentage. this simplifies to 5:95

5%Wheat bran

95% oats
