A teacher asked her students to divide a large number by 50.

• Aslan divided the number by 50.

• Lucy divided the number by 5 and then divided the answer she got by 10.

• Jack divided the number by 10 and then divided the answer he got by 40.

Who among these got the correct answer assuming they did NOT make mistakes in division?

Dear Student,

Let the number that Aslan, Lucy and Jack divide be x.Then, Aslan's result = x50Lucy's result = x5 ÷ 10 = x5 × 110 = x50Jack's result = x10 ÷ 40 = x10 × 140 = x400.Thus, Aslan and Lucy divided the number by 50, while Jack divided the number by 400, by their respective methods of division. Hence, Aslan and Lucy got the correct answer.
