Answer:
a) 12 ( I'm pretty sure)
Step-by-step explanation:
If the scale factor is positive than it is enlarged, and if it is a negative number than it is being reduced.
Let x = number of cups of ingredient B if 2 cups of ingredient A are used. Set up a proportion: (1/2)/(1 2/5) = (2)/x. Cross multiplying we get (1/2)x = (1 2/5)(2)
(1/2)x = 14/5, so x = 28/5 = 5 3/5 cups.
