Sorry it’s a bit messy. I tried going as fast as I could since this is due tomorrow for you.
2: I used a 2 off 2 on method. As an example, if the almonds are 5, I subtract 2 for the amount of raisins. If the raisins are 7, I add 2 for the amount of almonds.
3: I know that each row shows a ratio of 7 : 5 because all of them show raisins with a 2 less amount than the almond amount, as shown in the predid example.
