Question

solve also and taking lcm​

Answer 1

Hey Friend! Here's your answer,

4.

$= \frac{1}{3} - \frac{3}{4} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: lcm(12) \\ \\ = \frac{4}{12 } - \frac{9}{12} \\ \\ = \frac{ - 5}{12}$

5.

$= \frac{ - 3}{5} - \frac{ - 8}{9} \: \: \: lcm = 45 \\ \\ = \frac{ - 27}{45} - \frac{ - 40}{45} \\ \\ = \frac{13}{45}$

6.

$= 0 - \frac{ - 13}{9} \: \: lcm = 9 \\ \\ = \frac{0}{9} - \frac{ - 13}{9} \\ \\ = \frac{13}{9} = 1 \times \frac{4}{9}$
