What are rational and irrational numbers? ? i tried looking it up, but i still don't get it!

Step-by-step explanation:

This is a super question. The ancient Greeks knew about irrationals but because they were so weird, the Greeks decided that they were not numbers. I get the feeling students would agree with them.

A rational number is any number that can be represented as a fraction. 5/7 therefore is a rational number. So is 139 / 293 No matter how miserable the fraction is, eventually it will repeat.

Take 1/7 as an example 1/7 = 0.142857 The next number is a 1. The number after the 1 is a 4 and so on. So if I told you that the 5 occupies the place we are talking about, you'd be able to tell me that the next digit is a 7. 1/7 is rational which in plain talk 1/7 is well behaved.

The irrationals cannot be represented as a fraction. sqrt(5) is totally irrational. If I told you that the hundredth digit is a 5 (and I don't know if it is) you have a 1 in 10 chance of guessing the next number. Only a computer has the ability to figure out such a monster easily.

Leave a question if you don't understand. It will show up in my comments and I'll try and clear up the problem.

no not all of them.

step-by-step explanation:

some of them have a square base.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
