Answer :

10 17/18 is the answer so it’s C

Answer:

c. [tex]10\frac{17}{18}[/tex]

Step-by-step explanation:

[tex]-4\frac{5}{6} + 15\frac{7}{9}[/tex]

Change to improper fractions.

[tex]\\-4\frac{5}{6} = -\frac{29}{6} \\[/tex]

Multiply the whole number by the denominator and add that to the numerator.

[tex]15\frac{7}{9} = \frac{142}{9}[/tex]

Multiply the whole number by the denominator and add that to the numerator.

[tex]-\frac{29}{6} + \frac{142}{9}[/tex]

[tex]6: 6, 12, 18\\9: 9, 18[/tex]

Find a common denominator.

[tex]-\frac{29}{6} * 3 = -\frac{87}{18} \\\\\frac{142}{9} * 2 = \frac{284}{18} \\\\-\frac{87}{18} + \frac{284}{18}[/tex]

[tex]-\frac{87}{18} + \frac{284}{18} = \frac{197}{18}[/tex]

Add

[tex]10\frac{17}{18}[/tex]

Simplify
