\(\frac{25}{49}\)x \(\frac{21}{29}\)-\(\frac{25}{49}\)x\(\frac{7}{29}\)+ \(\frac{24}{49}\)x\(\frac{15}{29}\)

Answer 1

= 25/49 *( 21/29-7/29) +24/49 * 15/29

Answer 2

\(\frac{25}{49}.\frac{21}{29}-\frac{25}{49}.\frac{7}{29}+\frac{24}{49}.\frac{15}{29}\)

\(=\frac{25}{49}.\left(\frac{21}{29}-\frac{7}{29}\right)+\frac{24}{49}.\frac{15}{29}\)

\(=\frac{25}{49}.\frac{14}{29}+\frac{24}{49}.\frac{15}{29}\)

\(=\left(\frac{25}{49}+\frac{24}{49}\right).\left(\frac{14}{29}+\frac{15}{29}\right)\)

\(=1.1=1\)
