The problem asks for the value of the expression:
$ \frac{5}{3} + \left( \frac{1}{1 + \frac{4}{9}} \right) - \frac{2}{5} $
First, calculate the denominator inside the parentheses:
$ 1 + \frac{4}{9} = \frac{9}{9} + \frac{4}{9} = \frac{13}{9} $Now, calculate the entire term in parentheses:
$ \frac{1}{\frac{13}{9}} = \frac{9}{13} $The expression becomes:
$ \frac{5}{3} + \frac{9}{13} - \frac{2}{5} $The denominators are 3, 13, and 5. The least common multiple (LCM) of 3, 13, and 5 is:
$ \text{LCM}(3, 13, 5) = 3 \times 13 \times 5 = 195 $Combine the fractions using the common denominator:
$ \frac{325}{195} + \frac{135}{195} - \frac{78}{195} = \frac{325 + 135 - 78}{195} $Calculate the numerator:
$ \frac{460 - 78}{195} = \frac{382}{195} $The value of the given expression is $\frac{382}{195}$.
