15 pts! Please help with part A and part B!

Part A, in order from top to bottom, left to right:

Drink Tea: Yes: 280

Drink Tea: No: 120

Drink Tea at least 3 cups a day: Yes: 80

Drink Tea at least 3 cups a day: No: 200

Part B: 1/5 of 400 people drink 3 cups each day.

Step-by-step explanation:

Part A: No explanation needed, just filling in a table:

Part B: So the answer is 1/5. This is achieved by converting the percentage into a decimal, and in turn converting the decimal into a fraction.

If we are to convert 20% into a decimal, it becomes 0.20, and when we convert it into a fraction, it becomes 1/5.

Hope this helps.
