Can someone help me with my work?? i really need help you’ll get brainliest if you do

1. 5/8 cup is the total quantity of liquid ingredients.

2. 3 cups of chocolate chips.

Step-by-step explanation:

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).

5/8 cup 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.

3 cups is your final answer.

To note: the slashes (/) serve as a placeholder for a vinculum, or horizontal line between a numerator and denominator in a fraction.
