The statement 鈥�$-\frac{4}{5}+\left(-\frac{1}{3}\right)$.鈥�

When two fractions with different denominators are subtracted then the two unlike fractions, are converted into like fractions by multiplying the denominators with a common factor of their lowest common multiple (LCM).

Consider the provided statement 鈥�$-\frac{4}{5}+\left(-\frac{1}{3}\right)$.鈥�

Recall that when two fractions with different denominators are subtracted then the two unlike fractions, are converted into like fractions by multiplying the denominators with a common factor of their lowest common multiple (LCM).

LCM of 5 and 3 is 15.

So, multiply $\frac{4}{5}$by 3 and $\frac{1}{3}$by 5 in both numerator and denominator,

Thus, the given expression can be simplified as,

$-\frac{4}{5}+\left(-\frac{1}{3}\right)=-\frac{4脳3}{5脳3}+\left(-\frac{1脳5}{3脳5}\right)$

$-\frac{4}{5}+\left(-\frac{1}{3}\right)=-\frac{12}{15}+\left(-\frac{5}{15}\right)$

$-\frac{4}{5}+\left(-\frac{1}{3}\right)=-\frac{12}{15}-\frac{5}{15}$

$-\frac{4}{5}+\left(-\frac{1}{3}\right)=-\frac{17}{15}$

Since,$-\frac{17}{15}$ cannot be simplified further,

Hence, the simplified form of $-\frac{4}{5}+\left(-\frac{1}{3}\right)$is $-\frac{17}{15}$.
