Tenzin drinks 12\frac{1}{2} glass of milk every day. How many glasses of milk does he drink in a week? How many glasses of milk did he drink in the month of January?

Correct Answer

Given: Tenzin drinks 12\frac{1}{2} glass of milk every day.

Step 1: For a week, multiply days by daily consumption: 7×12=727 \times \frac{1}{2} = \frac{7}{2} Step 2: Convert to mixed fraction: 72=312\frac{7}{2} = 3\frac{1}{2} glasses ∴ Tenzin drinks 3123\frac{1}{2} glasses of milk in a week.

Step 3: For January (31 days): 31×12=31231 \times \frac{1}{2} = \frac{31}{2} Step 4: Convert to mixed fraction: 312=1512\frac{31}{2} = 15\frac{1}{2} glasses ∴ Tenzin drinks 151215\frac{1}{2} glasses of milk in January.

Explanation

The chapter explains multiplication of fractions with whole numbers. For a week (7 days): 7×12=72=3127 \times \frac{1}{2} = \frac{7}{2} = 3\frac{1}{2} glasses. For January (31 days): 31×12=312=151231 \times \frac{1}{2} = \frac{31}{2} = 15\frac{1}{2} glasses.

Solution Steps

  1. Step 1: For a week, multiply days by daily consumption: 7×12=727 \times \frac{1}{2} = \frac{7}{2}

  2. Step 2: Convert to mixed fraction: 72=312\frac{7}{2} = 3\frac{1}{2} glasses

  3. Step 3: For January (31 days): 31×12=31231 \times \frac{1}{2} = \frac{31}{2}

  4. Step 4: Convert to mixed fraction: 312=1512\frac{31}{2} = 15\frac{1}{2} glasses
