is 7.6 a rational number

Question

its for math and i dont know

Answer 1

A rational number is a number that can be expressed as a ratio (fraction).  The .6 in 7.6 is 6/10, so 7.6 = 7 ⁶/₁₀ = 76/10.  So, yes, it's a rational number.

 

Decimal numbers that never end and never repeat are irrational numbers.  So if the decimal ends, like 7.6, or it repeats, like 7.135135135135 ..., then it's rational.

Answer 2

7.6 is a rational number

a rational number is any number that can be expressed in the form a/b where a and b are integers and b≠0

7.6=7 6/10=76/10, 76 and 10 are integers and 10 is not equal to 0

Answer 3

A rational number is a number that has an end (or a unending, repeating number like 1.111111...). 7.6 has an end, so it is a rational number.

 

(Technically, a rational number is a number that can be represented as a fraction. 7.6 can be represented as 76/10, or 38/5. This is another way to determine if a number is rational.)
