Question

a) ` (135/2371 + 24/25) x (1/2 - 1/3 -1/6) `

Answer 1

\(\left(\dfrac{135}{2371}+\dfrac{24}{25}\right)\times\left(\dfrac{1}{2}-\dfrac{1}{3}-\dfrac{1}{6}\right)\)

\(=\left(\dfrac{135}{2371}+\dfrac{24}{25}\right)\times\left(\dfrac{3}{6}-\dfrac{2}{6}-\dfrac{1}{6}\right)\)

\(=\left(\dfrac{135}{2371}+\dfrac{24}{25}\right)\times0=0\)
