Answer 2

Answer:

21.75

Step-by-step explanation:

The given expression is

$20.25-9\dfrac{1}{2}+11$

We need to find the simplified form of the give expression.

$(20.25+11)-9\dfrac{1}{2}$

$31.25-9\dfrac{1}{2}$

Now simplify the mixed fraction.

$31.25-\dfrac{2(9)+1}{2}$

$31.25-\dfrac{18+1}{2}$

$31.25-\dfrac{19}{2}$

Taking LCM we get

$\dfrac{2(31.25)-19}{2}$

$\dfrac{62.5-19}{2}$

$\dfrac{43.5}{2}$

$21.75$

Therefore, the simplified form of the given expression is 21.75.
