Question

please help me anyone solve this ​

Answer 1

Step-by-step explanation:

$a) \frac{5}{7} - \frac{9}{7} = \frac{5 - 9}{7} = \frac{ - 4}{7} \\ \\ b) \frac{5}{9} - \frac{11}{3} = \frac{5}{9} - \frac{11 \times 3}{3 \times 3} = \frac{5}{9 } - \frac{33}{9} = \frac{5 - 33}{9} = \frac{ - 28}{9}$

$c) \frac{3}{8} - \frac{5}{12} = \frac{3 \times 12}{8 \times 12} - \frac{5 \times 8}{12 \times 8} = \frac{36 - 40}{96} = \frac{ - 4}{96} = - \frac{1}{24} \\ \\ d) \frac{2}{13} - \frac{11}{13} = \frac{2 - 11}{13} = \frac{ - 9}{13}$
