Question

using approprite properties find.
$- 2 \3 \times 3 \5 + 5 \2 - 3 \5 \times 1 \6$
​

Answer 1

$(- \frac{2}{3} \times \frac{3}{5}) + \frac{5}{2} - ( \frac{3}{5} \times \frac{1}{6} ) \\ \\ \implies( - \frac{6}{15} + \frac{5}{2}) - \frac{3}{30} \\ \\ \implies \frac{ - 12 + 75}{30} - \frac{3}{30} \\ \\ \implies \frac{ - 12 + 75 - 3}{30} \\ \\ \implies \: \frac{60}{30} \\ \\ \implies \frac{ \cancel{60}}{ \cancel{30}} = 2 \\ \\ \\ \\ \underline{\boxed{\sf{- \frac{2}{3} \times \frac{3}{5} + \frac{5}{2} - \frac{3}{5} \times \frac{1}{6} = 2 }}}$
