Reduce to simplest form. -\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)=− 8 7 −(− 6 5 )=minus, start fraction, 7, divided by, 8, e

slavikrds [6]

Answer:

$-\dfrac{1}{24}$

Step-by-step explanation:

We are required to reduce the expression below to its simplest form

$-\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)$

STEP 1: Remove the brackets

Take note that the product of same sign(- and -) will give you the addition sign.

$-\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)=-\dfrac{7}{8}+\dfrac{5}{6}$

STEP 2: Find the Lowest Common Multiple of 8 and 6

Lowest Common Multiple of 8 and 6 is 24

STEP 3: Use the LCM to Simplify

$-\dfrac{7}{8}+\dfrac{5}{6}=\dfrac{(-3X7)+(5X4)}{24}\\=\dfrac{-21+20}{24}\\=\dfrac{-1}{24}\\=-\dfrac{1}{24}$

Therefore:

$-\dfrac{7}{8}-\left(-\dfrac{5}{6}\right)=-\dfrac{1}{24}$
