Part A please. Possibly giving brainliest to the one who answers the question

Step-by-step explanation:

16 and 5/4 tbsp of sugar.

7 ÷ 2 = 3.5

Don't worry about the decimal for now, just find how many tbsp of sugar she needs for 6 tbsp of milk.

6 ÷ 2 = 3

3 x 5 = 15

Now, we will focus in the 0.5 tbsp of milk.

Find how much 1/2 a tbsp of milk can get for sugar.

4 1/2 tbsp of milk is 5 tbsp of sugar.

5 ÷ 4 = 1.25

So 16 and 5/4 tbsp of sugar is required.
