To determine the type of number resulting from the sum of \( \frac{2}{3} \) and \( \sqrt{25} \):
-
Calculate \( \sqrt{25} \): \[ \sqrt{25} = 5 \]
-
Now, add \( \frac{2}{3} \) and \( 5 \): \[ \frac{2}{3} + 5 = \frac{2}{3} + \frac{15}{3} = \frac{2 + 15}{3} = \frac{17}{3} \]
The result \( \frac{17}{3} \) is a rational number because it can be expressed as a fraction of two integers.
Thus, the correct type of number is option 1: rational.
The answer is: 1
