Simplify the following fraction by a factor of 9:
Let's simplify as follows, divide both the numerator and denominator by 9:
Without calculating, determine whether the quotient in the division exercise is less than 1 or not:
\( 5:6= \)
The problem asks us to simplify by a factor of 9. This means we must use 9 as our common factor. Since both 81 and 18 are divisible by 9, we can divide both by 9 to simplify.
Check the division: (no remainder) and (no remainder). If both divisions give whole numbers, then 9 is a valid common factor!
You would find the Greatest Common Factor (GCF) of 81 and 18. The GCF is actually 9, so you'd get the same answer! Always look for the largest number that divides both parts.
Let's check: cannot be simplified further because 9 and 2 share no common factors other than 1. This fraction is in its simplest form!
Common wrong answers happen when you don't divide both parts: dividing only 81 by 9 gives 9, or dividing 81 by 18 gives . Remember: both numerator and denominator must be divided by the same factor.
