An irrational number can become rational by dropping a few decimal?

Question

An irrational number can become rational by dropping a few decimal places.

a. true
b. false

i think its b not sure

Answer 1

Irrational numbers have an infinity of non-repeating numbers after the decimal point. There is no dropping a few from infinity, so b.

This question would become more rational if you dropped it into the mathematics category.
