Accepted Solution

A:
Answer:The ratio is 1 : 2 1/4Step-by-step explanation:The ratio would be 1 : 2 1/4 because if you look at the difference between batch 1 and 2, it has a difference of 1 in the amount of sugar, and 2 1/4 difference in the amount of flour. Compare it to batch 3, same thing. 2+1 is 3, and 4 1/2 = 4 2/4, and adding 2 1/4 would give you 6 3/4. This would make the ratio 3 : 6 3/4, but since it is the unit rate of change, the change ratio would be 1 : 2 1/4.
