To write the mixed number 1 1/3 as a whole number or a simplified fraction, you need to convert it to an improper fraction.

Step 1: Multiply the whole number (1) by the denominator of the fraction (3). In this case, you have 1 * 3 = 3.
Step 2: Add the product from step 1 to the numerator of the fraction (1). So, 3 + 1 = 4.
Step 3: Write the sum from step 2 as the numerator of the new fraction, keeping the same denominator. In this case, the denominator is still 3.
Step 4: Therefore, the improper fraction equivalent to 1 1/3 is 4/3.

Now, to express this fraction in its simplest form, you need to simplify it by finding the greatest common divisor (GCD) of the numerator and the denominator and dividing both by it.

Step 1: Find the GCD of 4 and 3. The only common factor is 1.
Step 2: Divide both the numerator (4) and the denominator (3) by the GCD. 4 ÷ 1 = 4 and 3 ÷ 1 = 3.
Step 3: The simplified fraction is 4/3.

Therefore, the simplified form of the mixed number 1 1/3 is 4/3.
