Question

What the rational number which should be subtracted from 16/9 to get 11/8.

Answer 1

Answer:

let the rational number be x

$\frac{16}{9} - x = \frac{11}{8} \\ \\ \frac{16}{9} - \frac{11}{8} = x \\ \\ \frac{16 \times 8}{72} - \frac{11 \times 9}{72} = x \\ \\ \frac{128}{72} - \frac{99}{72} = x \\ \\ \frac{29}{72} = x$
