Yes
√16 = 4
rational number
OpenStudy (milo123):
thanks!
for number 6 would the rational number be 5.4?
Mehek (mehek14):
Yes
It terminates so it's rational
OpenStudy (milo123):
that means that 5.3 is irrational?
Mehek (mehek14):
no
A number like 5.3548764768716161451 would be irrational because it goes on and has no pattern

Irrational numbers cannot be written as fractions
5.3 can be a fraction
