Answer 1

(17/7 + 15/9)-(11/7 + 5/9)

Answer 2

I can help you with math problems. To solve this expression, you need to add or subtract the fractions with the same denominator. To do that, you can multiply the numerator and denominator of each fraction by the least common multiple of the denominators. In this case, the least common multiple of 7 and 9 is 63. So, the expression becomes:

$$\left(\frac{2\times63+3\times9}{7\times9}+\frac{1\times63+6\times7}{9\times7}\right)-\left(\frac{1\times63+4\times9}{7\times9}+\frac{5\times7}{9\times7}\right)$$

Then, you can simplify the fractions by adding or subtracting the numerators and keeping the same denominator. The expression becomes:

$$\frac{189+27+63+42}{63}-\frac{63+36+35}{63}$$

$$\frac{321}{63}-\frac{134}{63}$$

Finally, you can subtract the fractions by subtracting the numerators and keeping the same denominator. The expression becomes:

$$\frac{321-134}{63}$$

$$\frac{187}{63}$$

This is the final answer. You can also write it as a mixed number by dividing the numerator by the denominator and writing the remainder as a fraction. The mixed number is:

$$2\frac{61}{63}$$
