Step-by-step explanation:

-7/8-(-5/6) = -7/8+5/6 =(-42+40) /48 = -1/24

Answer 2

Given-

$- \frac{7}{8} - ( \frac{ - 5}{6} )$

To find -

The value of

$- \frac{7}{8} - ( \frac{ - 5}{6} )$

Solution -

For addition or substraction of fraction number it is important that all the given fraction had same denominators.

LCM of 8 and 6 is 24.

Multiply 7/8 by 3/3 and 5/6 by 4/4 we get

$= - \frac{21}{24} - ( \frac{ - 20}{24} )$

When two negative sign multiplied addition occurred.

So,

$= - \frac{21}{24} + \frac{ 20}{24}$

$= \frac{ - 21 + 20}{24}$

When there is one negative sign and one positive sign then substraction occurred.

substract 20 from 21 we get

$= \frac{ - 1}{24}$

By dividing 1 by 24 we get

$= - 0.04$

(In decimal)

Hence,

The value of $- \frac{7}{8} - ( \frac{ - 5}{6} )$ is $\frac{ - 1}{24}$.
