Work out the following :
`1-2/3`

Answer

To solve the problem \( 1 - \frac{2}{3} \), we can follow these steps:

### Step 1: Convert the whole number to a fraction
We can express the whole number \( 1 \) as a fraction. Since any whole number can be written as itself over 1, we have:
\[ 1 = \frac{1}{1} \]

### Step 2: Find a common denominator
Next, we need to find a common denominator for the fractions \( \frac{1}{1} \) and \( \frac{2}{3} \). The denominators are \( 1 \) and \( 3 \). The least common multiple (LCM) of \( 1 \) and \( 3 \) is \( 3 \).

### Step 3: Convert the fractions to have the same denominator
Now, we convert \( \frac{1}{1} \) to a fraction with a denominator of \( 3 \):
\[ \frac{1}{1} = \frac{1 \times 3}{1 \times 3} = \frac{3}{3} \]

### Step 4: Subtract the fractions
Now that both fractions have the same denominator, we can subtract them:
\[ \frac{3}{3} - \frac{2}{3} = \frac{3 - 2}{3} = \frac{1}{3} \]

### Step 5: Write the final answer
Thus, the final answer is:
\[ 1 - \frac{2}{3} = \frac{1}{3} \]
