Multiplying a 2-digit number by
3 1/3
Select a 2-digit number.
Divide the number by 3.
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 x 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 x 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.
