Answer 1

Answer:

1. irrational number_

2. rational number

3. rational number

4. rational number

5. irrational number

Step-by-step explanation:

#2 root 5 is a non-terminating decimal that is that its remainder would never come as 0 hence its irrational number any whole number(in this case 5) subtracted from a irrational number is an irrational number

# it is a rational number because the answer obtained is zero

# rational number because on dividing both of them we would get 2/7

#irrational number as it's non-terminating

#irrational number as value of pie is non terminating
