Answer:
All are rational numbers.
Step-by-step explanation:
A rational number can be written in the form:
[tex] \frac{a}{b} [/tex]
where a and b are integers and b≠0.
We can rewrite 136 as
[tex] \frac{136}{1} [/tex]
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.
[tex] \sqrt{100} + 5 = 10 + 5 = 15[/tex]
15 is also an integer and hence an integer.
