Question

a) \(\dfrac{2,4\cdot12,6\cdot3,5}{6,3\cdot4,8\cdot31,5}\)

b) \(\dfrac{4,2\cdot8,7\cdot3,3}{1,1\cdot2,9\cdot2,1}\)

Answer 1

a: \(=\dfrac{24\cdot126\cdot35}{63\cdot48\cdot315}=\dfrac{1}{9}\cdot\dfrac{1}{2}\cdot2=\dfrac{1}{9}\)

b: \(=\dfrac{42\cdot87\cdot33}{11\cdot29\cdot21}=2\cdot3\cdot3=18\)

Answer 2

a)\(=\dfrac{24}{48}\times\dfrac{126}{63}\times\dfrac{35}{315}=\dfrac{1}{2}\times2\times\dfrac{1}{9}=\dfrac{1}{9}\)

b)\(=\dfrac{42\times87\times33}{29\times11\times21}=3\times2\times3=18\)
