Question

What number should be subtracted from 117/56 so as to get 31/28?

Answer 1

Step-by-step explanation:

Let the subtracted number be x

$\dfrac{117}{56} - x = \dfrac{31}{28}$

$x = \dfrac{117}{56} - \dfrac{31}{28}$

$x = \dfrac{117 - 31 \times 2}{56}$

$x = \dfrac{117 - 62}{56}$

$x = \frac{55}{56}$

55/56
