Answer: 48/72, simplified version is 2/3.
Step-by-step explanation: To find the answer, you have to multiply. Keep 6/8 but flip 9/8. Your equation should look like this: 6/8 x 8/9. Multiply the numerators first. 6 times 8 is 48. Next, multiply the denominators. 8 times 9 is 72. You should have this fraction: 48/72. You can simplify that by finding the greatest common factor that 48 and 72 have, which is 24. Do this to simplify: 48/72 divided by 24/24. 48 divided by 24 is 2 and 72 divided by 24 is 3. You should now have this fraction: 2/3. You can no longer reduce, so that's the answer.
