irrational right?
answer is 26.29638
OpenStudy (harman.singh):
Rational numbers are those which can be written as fractions. For eg. 1.5=3/2
Irrational numbers are those which cannot be written as fractions. For eg. 0.333 = ??
Does this help answer your question?
OpenStudy (518nad):
irrational has infinite decimals and it cannot be represented by an integer fraction
OpenStudy (jdm4iek):
hmm
OpenStudy (518nad):
this is rational

as there is a finite number of decimals , this can be represented as a fraction
OpenStudy (jdm4iek):
so what would 26.30 be in fraction form?
OpenStudy (harman.singh):
Do you think we can convert 26.29638 to a fraction?
OpenStudy (518nad):
for example
26.29638
=26296238/10000
OpenStudy (harman.singh):
Fraction form looks like this a/b . 26.30 is not in a fraction form

OpenStudy (jdm4iek):
so 1.5 is equal to 3/2
OpenStudy (518nad):
that is true
OpenStudy (jdm4iek):

@518nad Just wanted to finish those dots. :)
OpenStudy (518nad):
><
OpenStudy (jdm4iek):
ok back on track peeps XD
OpenStudy (518nad):
okay let me help you understand decimals its much easier than u think okay
OpenStudy (518nad):
so take a look at any number lets say
123.12

OpenStudy (518nad):
every place of a number of telling u some unit of 10^n
OpenStudy (518nad):
for example in
123.45
you have 3 in 1s place
2 in 10s place
1 in 100s place
4 in 1/10s place
5 in 1/100s place
OpenStudy (518nad):
have you ever seen something like this before?
OpenStudy (jdm4iek):
yep
OpenStudy (518nad):
okay so any number you see can be written as a sum of these things

26.30 means
you have
6 in 1s place
2 in 10s place
3in 1/10s place
0 in 1/100s place
OpenStudy (jdm4iek):
yeah
OpenStudy (518nad):
so u have
6*1 + 2*10 + 3 *1/10 + 0 * 1/100
OpenStudy (jdm4iek):
i understand decimals
OpenStudy (518nad):
can you add these fractions together

26.30
2in 10s place
6 in 1s place
3 in 1/10s
so you have 2 of 10, 6 of 1 and 3 of 1/10
2*10 + 6*1 +3 *1/10 = ??
OpenStudy (518nad):
do not use calculator use your fraction addition skills
OpenStudy (jdm4iek):
dangit
OpenStudy (jdm4iek):
2x10=20
6x1= 6
3x1/10 = 0.3
26..3
OpenStudy (518nad):
keep it as a fraction buddy throw away decimals

OpenStudy (518nad):
what is
26 + 3/10
OpenStudy (518nad):
26/1 + 3/10
OpenStudy (518nad):
we need common denominator to add fractions
OpenStudy (jdm4iek):
ok

can you
find this
26/1 = ___/10
what goes in the blank
OpenStudy (jdm4iek):
3?
OpenStudy (518nad):
nono i just wanna rewrite 26/1 as a denominator with 10 now
OpenStudy (518nad):
so that we can add it to 3/10
OpenStudy (jdm4iek):
so should we divide 26 / 10?

OpenStudy (518nad):
that is no longer the same as 26/1 though is it
OpenStudy (518nad):
look we want to add these 2
26/1 + 3/10
but they dont have same denominator
we need to express 26 in another way with 10 as denominator
OpenStudy (518nad):
260/10 = 26/1
OpenStudy (jdm4iek):
oooohh
OpenStudy (jdm4iek):
i feel dumb :/
keep goin though

mhm now
26/1 + 3/10
=260/10+3/10
=263/10
OpenStudy (518nad):
its okay you just gotta understand fractions
OpenStudy (jdm4iek):
now we have 263/10
OpenStudy (518nad):
right which is 26.3

ok youre the boss
OpenStudy (518nad):
okay you need to understand 2 or 3 main things to really get fractions
OpenStudy (jdm4iek):
alright
OpenStudy (518nad):
what a whole is, and what it makes to take parts of wholes, and how we can think about adding parts.
2nd is understanding fraction to decimal conversion

OpenStudy (518nad):
fractions when the denominator is some power of 10 can rewritten as a decimal
OpenStudy (518nad):
and you need to understand what equivalent fractions are and why they are equal
and thats pretty much everything
