Answer:
a rational number
Explanation:
3.4 is a terminating decimal. That means that after the 4 in 3.4 there are no other numbers (the number "ends" after the 4) Also, 3.4 can be written as a RATIO of two numbers (looks like a fraction)
3.4 = 3 4/10 = 3 2/5
= 15/5 + 2/5
= 17/5
If you put 17÷5 in a calculator it would say 3.4
3.4 = 17/5
3.4 is a rational number.
