Question

Which of the following is not a rational number 43.123456,0.120120012000-----22by7 ​

Answer 1

Answer:

.0130130012000___

rational numbers are those which can be expressed in fractions(p/q)

first one - 43.123456 =44123456/1000000✓

third one - 22/7 (also if solved we will get a sequence decimal number which is considered to be a rational number)

thence we are left with 0,1201...where there is no sequence , we can't express using a fraction(like wise 22/7 and 3.14 is rational but π is not)

hope it help comment if not cleared
