Question

What number should be subtracted from -13/6 to get -5 ?

Answer 1

Answer:

-13/6 -x=-5

-13/6+5=x

LCM of 6,1 is 6

17/6=x

Answer 2

➤ Answer :-

$\tt\longrightarrow \dfrac{( - 13)}{6} - ( \sf x) \: \tt = ( - 5)$

To find the value of 'x' in the following sum we should subtract $\tt\dfrac{(-13)}{6}$ and (-5).

$\sf\longrightarrow (x) \: \tt = \dfrac{( - 13)}{6} - ( - 5)$

$\tt\longrightarrow \dfrac{( - 13)}{6} - \dfrac{( - 5)}{1}$

Convert them into like fractions by taking the LCM of the denominators i.e, 6 and 1.

LCM of 6 and 1 is 1.

$\tt\longrightarrow \dfrac{( - 13)}{6} - \dfrac{( - 5) \times 6}{1 \times 6}$

$\tt\longrightarrow \dfrac{( - 13)}{6} - \dfrac{( - 30)}{6} = \dfrac{( - 13) - ( - 30)}{6}$

$\tt\longrightarrow \dfrac{( - 13) + 30}{6}$

$\tt\longrightarrow \dfrac{17}{6} = 2 \dfrac{5}{6}$

$\Huge\therefore$The other number is $\tt 2 \dfrac{5}{6}$.
