Hi,

Yes, 0.1 is a rational number because we can express it as a ratio/fraction. Notice that the 1 is in the tenths place and therefore we can say: 1 / 10 = 0.1.

FINAL ANSWER 0.1 = 1 / 10

I hope that helps you out! Please let me know if you have any other questions!

Rational. It is a fraction, 1/10.

rational are none # that stop or are repeating #s like .333333...... or .45 .

irrational #s are #s that are non terminating non repeating numbers like .2135461564641001321653102130..............


so therefore .1 is a rational # because its a number that stops. just like the # .45.
