🎙️
Use factoring to help you divide these fractions
🎙️
Dividing by a fraction is the same as multiplying by its inverse, so let's flip the fraction and multiply
🎙️
Now let's find the prime factorization of each number
🎙️
Multiplying fractions is the same as multiplying top and multiplying bottom
🎙️
Now we can cancel matching terms on top and bottom
🎙️
So our fraction simplifies to 10 over 9
