The sum is rational or irrational number?

Gnesinka [82]

Answer:

a rational number

Step-by-step explanation:

1) First, find the sum of $\frac{4}{7} +\frac{-1}{3}$ :

$\frac{4}{7} + \frac{-1}{3} \\= \frac{12}{21} - \frac{7}{21} \\= \frac{5}{21}$

2) Any number that can be written as a fraction is a rational number. Therefore, the sum, $\frac{5}{21}$ , is rational.
