Questions & Step-by-Step Solutions

If a person needs 300 mg of calcium daily and a glass of milk provides 100 mg, how many glasses of milk must they drink to meet their daily requirement? (2020)
  • Step 1: Identify how much calcium the person needs daily. In this case, it is 300 mg.
  • Step 2: Identify how much calcium is in one glass of milk. Here, it is 100 mg.
  • Step 3: To find out how many glasses of milk are needed, divide the total calcium needed (300 mg) by the amount of calcium in one glass of milk (100 mg).
  • Step 4: Perform the division: 300 mg ÷ 100 mg = 3.
  • Step 5: Conclude that the person must drink 3 glasses of milk to meet their daily calcium requirement.
  • Division – The question tests the ability to divide the total calcium requirement by the amount provided per glass to find the number of glasses needed.
  • Unit Conversion – Understanding that both the requirement and the amount provided are in the same unit (mg) is essential for solving the problem.
