For this, let us change units of 9 from meters to centimeters. We know that 1 meter is equal to 100 centimeters. Therefore, 9 meter will be equal to 9×100=900 centimeter. Hence, we need to find the ratio of 900cm to 27cm or we can say 900 to 27.

To Verify the following (−21)×[(−4)+(−6)]=[(−21)×(−4)]+[(−21)×(−6)] Taking LHS we have (−21)×[(−4)+(−6)] =(−21)×[−4−6] =(−21)×(−10) =210 Now , Taking RHS we have [(−21)×(−4)]+[(−21)×(−6)] =84+126 =210 Hence , LHS = RHS
