Show answer & explanation
Answer: 2
Step 1: total juice in milliliters (5 liters × 1000) = 5000 Step 2: how many full 300 ml bottles can be filled (5000 ÷ 300) = 16 Step 3: juice left over after filling those bottles (5000 − 16 × 300) = 200 Step 4: bottles each of 6 people gets if they're shared equally, ignoring leftovers (16 ÷ 6) = 2 So the answer is 2 — bottles per person.

10Maya needs to seat 140 guests at tables that each seat exactly 6 guests. What is the fewest number of tables needed so that every guest has a seat?
