Answer

(a) It is wrong because the answer is greater than one when it should be less than one. (b) 0.55

Work Step by Step

When the denominator of a fraction is greater than the numerator, then its value is less than one. Keith made the mistake of dividing 9 divided by 5 rather than 5 divided by 9 as the fraction correctly reads. The correct solution to the problem is 5$\div$9=0.55.
