Question

$\frac{2}{5} \times \frac{ - 3}{ 7} - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5}$
​using oppropriaties properties find​

Answer 1

GIVEN:-

• $\frac{2}{5} \times \frac{ - 3}{ 7} - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5}$
• using oppropriaties properties find

SOLUTION:-

• 2/5×(−3)/7−1/14−3/7×3/5

• $\implies$2/5×(−3)/7−3/7×3/5−1/14

Taking common term, we get

• $\implies$(−3)/7(2/5+3/5)−1/14

• $\implies$(−3)/7×(2+3)/5−1/14

• $\implies$(−3)/7−1/14

Taking L.C.M. we get,

• $\implies$(−6−1)/14

$\implies$(−7)/14

• $\implies$(−7÷7)/(14÷7)

We get,

• $\implies$(−1)/2.

hope it helped!

using oppropriaties properties find

SOLUTION:-

2/5×(−3)/7−1/14−3/7×3/5

\implies⟹ 2/5×(−3)/7−3/7×3/5−1/14

Taking common term, we get

(−3)/7(2/5+3/5)−1/14

\implies⟹ (−3)/7×(2+3)/5−1/14

\implies⟹ (−3)/7−1/14

Taking L.C.M. we get,

(−6−1)/14

=>(−7)/14

=>(−7÷7)/(14÷7)

We get,

=> (−1)/2.
