Question

I still dont kinda get the difference between rational and irrational numbers.

Answer 1

@kitty10280 Help me please

Answer 2

Rational numbers are those that can be expressed as m/n for integer m and n. Some rational numbers are 1/3, 0.8, and 10. Some irrational numbers are pi, the square root of 3, and 2 to the 3/2 power.

Answer 3

So how would I go about finding a irratinal number in 5.2 and 5.5?

Answer 4

are you still having trouble with this @david954954 ?

Answer 5

Yes

Answer 6

since you know pi is irrational use this...
what number can you add to pi that will put you between the numbers 5.2 and 5.5

Answer 7

there are many numbers
just think of one number

Answer 8

8?

Answer 9

you do know pi is approximately 3.14159 ?

Answer 10

so if I add that to 8
I would get something bigger than 11

Answer 11

Yes

Answer 12

11 is not between 5.2 and 5.5

Answer 13

3.14159+ what number will be a number between 5.2 and 5.5 ?

Answer 14

so It has to be the lowest?

Answer 15

i'm not sure what you are referring to
you do see why 3.14159+8 isn't between 5.2 and 5.5 right?

Answer 16

Yeah

Answer 17

So I have to add pi and get a number between 5.2 and 5.5?

Answer 18

I'm asking you to choose a number such that when you add it to pi
you get a number between 5.2 and 5.5

Answer 19

So 2

Answer 20

you are getting closer
2+3.14159 is 5.14159 which is still not between 5.2 and 5.5

but it is very close

Answer 21

what is 2.1+pi ?

Answer 22

approximately

Answer 23

5.241

Answer 24

is that a number between 5.2 and 5.5?

Answer 25

Yeah

Answer 26

yep yep
2.1+pi is one answer you could choose

there are infinitely many more answers though
however your question just asked for one
and you did that

Answer 27

Oh ok so its 5.2?

Answer 28

how did you get 5.2 from 2.1+pi
are you trying to round 2.1+pi to the nearest hundredth ? if so that is incorrect since you have rounded to the nearest tenth instead.

Answer 29

Wait what?

Answer 30

I don't understand where 5.2 is coming from

Answer 31

we got 2.1+pi earlier

Answer 32

this is not 5.2

Answer 33

and then I was trying to figure out if you were trying to do the other part of the question which says to round to the nearest hundredth
if so you did not do this
you rounded to the nearest tenth instead

Answer 34

Oh ok yeah sorry. I got confused

Answer 35

so the awnser was 5.241 right

Answer 36

2.1+pi rounded to the nearest hundreth means to look at the 2nd number to the right of the decimal and use the 3rd number to the right of the decimal to figure out if you need to round the 2nd number up or leave the same

Answer 37

and I should use the word digit instead of number

Answer 38

the 2nd digit to the right of the decimal is 4
the 3rd digit to the right of the decimal is 1
1 is less than 5 that means we are going to leave the 2nd digit the same

so what is 2.1+pi rounded to the nearest hundredth ?

Answer 39

52.41

Answer 40

5.241 rounded to the nearest hundredth is not going to be 52.41
52 is way bigger than 5
this is not a good rounding

Answer 41

it isn't a rounding at all :p

Answer 42

shouldn't it stay the same then?
