Question

3. Find the sum
answer me please​

Answer 1

Step-by-step explanation:

$(i) \: \frac{1}{17} + \frac{5}{34} \\ = \frac{1 \times 2}{17 \times 2} + \frac{5}{34} \\ = \frac{2 + 5}{34} \\ = \frac{7}{34}$

$(iv) \: \frac{5}{17} + \frac{9}{68} \\ = \frac{5 \times 4}{17 \times 4} + \frac{9}{68} \\ = \frac{20}{68} + \frac{9}{68} \\ = \frac{20 + 9}{68} \\ = \frac{29}{68}$

$(vii) \: 2 \frac{1}{3} + \frac{6}{7} \\ = \frac{7}{3} + \frac{6}{7} \\ = \frac{7 \times 7}{3 \times 7} + \frac{6 \times 3}{7 \times 3} \\ = \frac{49 + 18}{21} \\ \\ = \frac{67}{21}$
