STEP Δ1Δ find the least common denominator/multiple of 8 and 9. 2/8= 18/72. 3/9= 24/72. Step 2 Add. 18+24= 42. Step 3 Simplify. 42/62= 21/36= 7/12. Once you reach 7/12, you can no longer simplify. So, your final answer is 7/12, or seven twelths (even though that not how you spell it). Hope this helps ;). Thank you and have a super awesome day.
