Question

using appropriate properties find
-3/4×5/6+4/5-3/5×3/4​

Answer 1

Answer:

$\frac{ - 11}{40}$

Step-by-step explanation:

$\frac{ - 3}{4} \times \frac{5}{6} + \frac{4}{5} - \frac{3}{5} \times \frac{3}{4} \\ \\ - \frac{3}{4} \times \frac{5}{6} - \frac{3}{5} \times \frac{3}{4} + \frac{4}{5} \\ \\ \frac{ - 3}{4} ( \frac{5}{6} + \frac{3}{5} ) + \frac{4}{5} \\ \\ \frac{ - 3}{4} ( \frac{43}{30} ) + \frac{4}{5} \\ \\ - \frac{43}{40} + \frac{4}{5} \\ \\ \frac{ - 43 + 32}{40} \\ \\ \frac{ - 11}{40}$
