Move the decimal point one place to the right (or add a zero).

Example:

The 2-digit number chosen to multiply by 3 1/3 is 78.

Divide by 3: 78/3 = 26

Add a zero: 260

So 78 × 3 1/3 = 260.

See the pattern?

The 2-digit number chosen to multiply by 3 1/3 is 29.

Divide by 3: 29/3 = 9.6 2/3

Move the decimal point one place to the right: 96 2/3

So 29 × 3 1/3 = 96 2/3.

If the division does not come out even, divide to one decimal place and express
the result as a fraction. Your answer will be a mixed number when you move the decimal
point one place to the right.
