Question

Can some help me ^_^

Answer 1

^_^

Answer 2

you could apply PEMDAS to this

Answer 3

?

Answer 4

P = ( ) E = exponent M = multiplication D = division A = addition S = subtraction

Answer 5

oh that yea

Answer 6

Could you tell us what your answer would be?

Answer 7

one min

Answer 8

This is what we have \[\frac{ 3*1.5-2.5 }{ 4(8.62-6.37) }\]

Answer 9

look at the denominator. what operation would we do first?

Answer 10

\[\frac{ 99 }{ 32}\]

Answer 11

\[\frac{ 2.4 }{ 4}\]

Answer 12

let's look at the denominator: we have 4(8.62-6.37) reading what I showed you about pemdas, which operation would you do first?

Answer 13

hmmm?

Answer 14

so the order is ( ) then exponent then multiplication then division addition then subtraction, we need to always do what's in the ( ) first

Answer 15

division

Answer 16

so I should have told you the way i approach this is that I work with the numerator and denominator separately

Answer 17

on the bottom we have 4(8.62-6.37) so the first thing we would do is the ( ) and we would have to subtract 8.62-6.37 because that's what's in the ( ) that's where PEMDAS comes from. then after that we multiply by 4 because that's the next operation

Answer 18

@alivejeremy do you follow?

Answer 19

yea

Answer 20

what would you get in the denominator?

Answer 21

\[\frac{ 2.5 }{ ? }\]

Answer 22

\[\frac{ ? }{ 2.5 }\]

Answer 23

@Photon336 do u follow

Answer 24

?

Answer 25

^_^

Answer 26

okay 4(8.62-6.37) this is in the denominator

we do what's in the ( ) first and we get 2.25 this is from subtracting 8.62-6.37 right?

then the next step is to then multiply by 4 so we do 4*2.25 and we get 9 so that's for the denominator

Answer 27

woo?

Answer 28

i give up

Answer 29

noo not yet. what do you think PEMDAS means?

Answer 30

I think you need to understand that better first then the problem is easy

Answer 31

PEMDAS is an acronym for the words parenthesis, exponents, multiplication, division, addition, subtraction. Given two or more operations in a single expression, the order of the letters in PEMDAS tells you what to calculate first, second, third and so on, until the calculation is complete. If there are grouping symbols in the expression, PEMDAS tells you to calculate within the grouping symbols first.

Answer 32

right

Answer 33

so let's say if i had 3*1.5-2.5 what do you see here? what operations

Answer 34

you'll get this just work with me

Answer 35

ok

Answer 36

i tryed to work it out 1000 times

Answer 37

but tell me first what operations do you see here 3*1.5-25

Answer 38

time

Answer 39

what else?

Answer 40

subtract

Answer 41

okay great now let's go back to

PEMDAS

tell me what operation should you do first, and what should be second?

Answer 42

so you know you have multiplication and subtraction, which would you do first and why?

Answer 43

multiplication

Answer 44

:) good

Answer 45

because it comes first

Answer 46

exactly

Answer 47

so in this problem 3*1.5-2.5

Answer 48

looking at PEMDAS how would you solve this?

Answer 49

2

Answer 50

its @ right @Photon336

Answer 51

@alivejeremy that's correct. you see this is not that bad once you apply PEMDAS

Answer 52

true

Answer 53

\[\frac{ 2}{ ? }\]

Answer 54

2/4

Answer 55

now let's work with the denominator again:

4(8.62-6.37)

1. tell me what operations are in this part
2. tell me what you would do first based on PEMDAS

Answer 56

@alivejeremy remember whenever there are ( ) you need to do whatever is in those first

Answer 57

ok

Answer 58

subtraction

Answer 59

@Photon336

Answer 60

Yes @alivejeremy but why?

Answer 61

because thats all i see lol

Answer 62

and it comes first

Answer 63

lol the answer I was looking for is because subtraction is inside the ( ) and that's why we do it first. so now that you know that whats the answer? for the denominator?

Answer 64

2.25

Answer 65

@Photon336

Answer 66

@alivejeremy nice how one last thing remember you had 4 multiplied by the whole thing

Answer 67

2.25 * 4

Answer 68

:) so what's your final answer both numerator and denominator?

Answer 69

\[\frac{ 2 }{ 9 }\]

Answer 70

yep

Answer 71

there we go man you got it

Answer 72

thanks friend

Answer 73
