Question

How much is 17 5/14 - 18

Answer 1

Given:

`17(5)/(14)-18`

To solve the expression, we convert the mixed number to an improper fraction and find the lowest common denominator (LCD) of both fractions.

The LCD is 14.

`\begin{gathered} 17(5)/(14)-18=(243)/(14)-(18)/(1) \\ =(243-252)/(14) \\ =(-9)/(14) \end{gathered}`

Therefore, the answer is;

`(-9)/(14)`
