Question 881479: Good Day Hi mam/sir. can you help me answering those questions ?
Use both the roster and rule method to specify the sets of the following:
1. The counting numbers less than 25.
2. The fraction whose numerator is 1 and whose denominator is a multiple of 5.
3. The single even number greater than 0 but lessthan 10.
And please mam/sir explain to me how to solve that. So that, I will also learn. Thankyou ! Godbless

You can put this solution on YOUR website! Use both the roster and rule method to specify the sets of the following:
1. The counting numbers less than 25.
roster:: 1,2.3.4...20,21,22,23,24
rule:: {x | x E N and 1<= x <=24}
========================================
2. The fraction whose numerator is 1 and whose denominator is a multiple of 5.
roster:: 1/5, 1/10, 1/15...
rule:: {x | x = 1/(5n) where n E N}
==================================================
3. The single even number greater than 0 but less than 10.
roster: 2,4,6,8
rule:: {x | x = 2n where n = 1,2,3,4}
=================================================
Cheers,
Stan H.
