Now prove to yourself with your calculator that your answer is correct. Calculate the answers to 3 divided by 4, 9 divided by 16, and divide the first answer by the second answer. Now calculate 4 divided by 3. If you are correct, the answers are the same (equivalent) and you have successfully divided by fraction by a second fraction.
