Question

By what number should(-16/21) be divided so that the quotient may be (-4)7?

Answer 1

(33/8)/x = 11/2

33/8 = (11/2) * x

x = (33/8)/(11/2)

Using the J programming language:

J defines rational fractions with an ‘r’. i.e, 33r8, 11r2

J defines division by ‘%’. Type the equation in the J interpreter:

33r8 % 11r2

3r4

So the answer is 3r4 - (3/4).
