Final answer:
To divide the sum of two fractions by their difference, add the fractions, subtract the fractions, and divide the sum by the difference.
Step-by-step explanation:
To divide the sum of two fractions by their difference, follow these steps:
- Add the two fractions together to get the sum.
- Subtract the two fractions to get the difference.
- Divide the sum by the difference.
Let's apply these steps to the given problem:
- Add 97/15 and 12/5:
97/15 + 12/5 = (97 * 5 + 12 * 15)/(15 * 5) = 485/75 - Subtract 97/15 and 12/5:
97/15 - 12/5 = (97 * 5 - 12 * 15)/(15 * 5) = (485 - 180)/75 = 305/75 - Divide the sum by the difference:
(485/75) ÷ (305/75) = (485/75) * (75/305) = 485/305 = 1.5902
Therefore, the division of the sum of 97/15 and 12/5 by their difference is approximately 1.5902.
