Question

what should be subtract from - 5/6 to get - 31/14​

Answer 1

Answer:

-5/6-x=31/14

x=31/14+(-5/6)

x=31/14-5/6

x=31*3/14*3-5*7/6*7

x=93/42-35/42

x=58/42

Answer 2

➤ Answer :-

$\tt \longrightarrow \dfrac{( - 5)}{6} - \sf(x) = \tt \dfrac{( - 31)}{14}$

To find the value of 'x' in the given sum, we should subtract the first value i.e, $\tt\dfrac{(-5)}{6}$ and the answer obtained i.e, $\tt\dfrac{(-31)}{14}$

$\tt \longrightarrow \sf(x) = \tt \dfrac{( - 5)}{6} - \dfrac{( - 31)}{14}$

Convert them into like fractions by taking the LCM of the denominators i.e, 6 and 14.

LCM of 6 and 14 is 42.

$\tt \longrightarrow \dfrac{( - 5) \times 7}{6 \times 7} - \dfrac{( - 31) \times 3}{14 \times 3}$

$\tt \longrightarrow \dfrac{( - 35)}{42} - \dfrac{( - 93)}{42} = \dfrac{( - 35) - ( - 93)}{42}$

$\tt \longrightarrow \dfrac{( - 35) + 93}{42} = \dfrac{58}{42} = \boxed{\tt 1 \dfrac{16}{42} }$

$\Huge\therefore$The other rational number to be subtracted is $\tt 1 \dfrac{16}{42}$
