$\left(+\frac{3}{5}\right)+\left(-\frac{7}{5}\right)$
\(\boxed{-0.8}\) is the final answer
Step 1 :Given the problem \(\left(+\frac{3}{5}\right)+\left(-\frac{7}{5}\right)\)
Step 2 :This is a simple addition of two fractions. The fractions already have the same denominator, so we can directly add the numerators. The operation is as follows: \(\left(+\frac{3}{5}\right)+\left(-\frac{7}{5}\right) = \frac{3 - 7}{5}\)
Step 3 :Calculate the numerator: 3 - 7 = -4
Step 4 :The denominator remains the same: 5
Step 5 :Simplify the fraction to get the final result: \(-\frac{4}{5} = -0.8\)
Step 6 :\(\boxed{-0.8}\) is the final answer
