20% of 135 pounds is (20/100) x 135 = (1/5) x 135 = 27 So 135 pounds minus 20% discount = 135 - 27 = 108 Another way of looking at this is that after a discount of 20% the object really costs only 80% of the original price, hence 135 pounds minus 20% discount = 80% of 135 = (80/100) x 135 = (8/10) x 135 which is equal to (4/5) x 135 = 4 x 27 = 108
Since 15 is a factor of 135, it is automatically the GCF.
