Answer 1

Answer:

$\sf a) \: \frac{34}{39}$

$\sf b) \: \frac{22}{27}$

$\sf c) \: \frac{36}{42}$

$\sf d) \: \frac{15}{23}$

Step-by-step explanation:

$\sf a) \: \frac{11}{39} + \frac{23}{39} = \frac{11 + 23}{39} = \frac{34}{39}$

$\sf b) \: \frac{7}{27} + \frac{15}{27} = \frac{7 + 15}{27} = \frac{22}{27}$

$\sf c) \: \frac{13}{42} + \frac{23}{42} = \frac{13 + 23}{42} = \frac{36}{42}$

$\sf d) \: \frac{9}{23} + \frac{6}{23} = \frac{9 + 6}{23} = \frac{15}{23}$
