Answer:To add 10 and 1/3 plus 7/9, you need to first convert 10 to a fraction with the same denominator as 1/3 and 7/9.
Here's a step-by-step approach:
1. Convert 10 to a fraction with the same denominator as 1/3 and 7/9. The common denominator for 1/3 and 7/9 is 9. So, 10 can be written as 90/9.
2. Now, you have 90/9 + 1/3 + 7/9.
3. To add these fractions, you need to make sure they have the same denominator. Since they already share a common denominator of 9, you can directly add the numerators.
4. Adding the numerators: 90 + 3 + 7 = 100.
5. The sum of 90/9 + 1/3 + 7/9 is 100/9.
6. You can simplify the fraction 100/9, which equals 11 and 1/9.
Therefore, 10 and 1/3 plus 7/9 equals 11 and 1/9.
