Answer 2

`= (17 xx 21 xx 7 xx 9)/(17 xx 21 xx 35 xx 45)`

`= ( 7 xx 9)/(7 xx 5 xx 9 xx 5)`

`= 1/25`

Answer 3

17/35 x 21/45 x 7/17 x 9/21 = ( 17/35 x 7/17 ) x ( 21/45 x 9/21 )

\(\dfrac{17}{35}\times\dfrac{21}{45}\times\dfrac{7}{17}\times\dfrac{9}{21}=\dfrac{17}{75}\times\dfrac{7}{17}\times\dfrac{9}{21}=\dfrac{7}{75}\times\dfrac{9}{21}=\dfrac{1}{25}\)
