Question

How do you simplify this expression

Answer 1

Convert 6\frac{3}{8}6​8​​3​​ to improper fraction. Use this rule: a \frac{b}{c}=\frac{ac+b}{c}a​c​​b​​=​c​​ac+b​​:
​∣8​​6×8+3​​−2∣+∣−8​8​​5​​−1∣


Simplify 6\times 86×8 to 48:
​8​​48+3​​−2∣+∣−8​8​​5​​−1∣


Simplify 48+348+3 to 51:
​8​​51​​−2∣+∣−8​8​​5​​−1∣

Make the denominators the same:
51​​/8−2×​8​​8​​

Simplify. Denominators are now the same:

51​​/8−​8​​16​​

Join the denominators: \frac{51-16}{8}​8​​51−16​​

etc.. and your answer will be 14
