Algebra (Diagnostic Test): What's Wrong? (II)

Do you know where has gone wrong?

  1. The working is wrong because 10a / 5b is the same as [10 x a] / [5 x b] and because you have to work out the brackets first, you cannot write it as 10 x a x 1/5 x b. the correct working should be :

    10a / 5b
    =2a / b
