<em>Answer:</em>
1. <u>5/8 cup is the total quantity of liquid ingredients.</u>
2. <u>3 cups of chocolate chips.</u>
<em>Step-by-step explanation:</em>
1. Since the milk (1/4) and oil (3/8) have different denominators, we have to multiply the lower of the two to have equivalent denominators to each other. So, it would be (1x2=2, and 4x2=8), thus the expression would be 2/8 + 3/8, which would come out to be 5/8 (keep the common denominator, add the numerators).
<u>5/8 cup</u> is your final answer.
2. Since we are "doubling", we need to multiply the current amount of chocolate chips by 2. So, we would do 1 1/2x2. This would result in 3 total, because 1+1=2 and 1/2+1/2=1, so 2+1=3.
<u>3 cups</u> is your final answer.
