\(=\dfrac{12}{15}\times\left(\dfrac{26}{11}-\dfrac{9}{11}-\dfrac{6}{11}\right)=\dfrac{12}{15}\times\dfrac{11}{11}=\dfrac{12}{15}=\dfrac{4}{5}\)
= 12/15 x (26/11 - 9/11 - 6/11)
= 12/15 x 11/11
= 12/15
12/15 x 26/11 - 12/15 x 9/11 - 12/15 x 6/11
= 12/15 x ( 26/11 - 9/11 - 6/11)
= 12/15 x 1
= 12/15
`12/15 xx 26/11 - 12/15 xx 9/11 - 12/15 xx 6/11`
`= 12/15 xx ( 26/11 - 9/11 - 6/11)`
`= 12/15 xx 1`
`= 12/15`
