Step-by-step explanation:

Answer 2

Answer:

All are rational numbers.

Step-by-step explanation:

A rational number can be written in the form:

$\frac{a}{b}$

where a and b are integers and b≠0.

We can rewrite 136 as

$\frac{136}{1}$

hence 136 is a rational number.

715-245=470....is an integer and hence a rational number.

(47)(217)=10199....which is an integer, and all integers are rational numbers.

$\sqrt{100} + 5 = 10 + 5 = 15$

15 is also an integer and hence an integer.
