Question

How do you do this type math problem example
1/5x +8= 3/4 these are fractions if you can't tell.

Answer 1

\[\frac{ x }{ 5 }+8=\frac{ 3 }{ 4 }\]

You need to get x 'on its own' so first multiply the whole equation by 5 to remove the fraction under x

write your answer here..

Answer 2

x/25 + 40= 15/20

Answer 3

not quite correct - the first term is not right - we are trying to get x on its own

Answer 4

The teacher showed the class this but I didn't really get it and she couldn't explain it for me understand to help me.

Answer 5

Well - you have done MOST of the work - I asked you to multiply the equation by 5 (because we have x/5 in the equation)

You have made a mistake in the first term:

5 (x/5 + 8) =?

Answer 6

x/25 + 40 is this part right?

Answer 7

no - as I said it is the first term

5 (x/5)=?

Answer 8

The way the teacher said it I thought it went as 1/20x +40

Answer 9

you could just add the fractions
bear in mind that \(\bf \cfrac{ x }{ 5 }+8=\cfrac{ 3 }{ 4 }\implies \cfrac{ x }{ 5 }+\cfrac{8}{1}=\cfrac{ 3 }{ 4 }\implies \cfrac{ x }{ 5 }+\cfrac{8}{1}-\cfrac{ 3 }{ 4 }=0\)

then just get the LCD and sum the fractions

then multiply both sides by the found LCD, then solve for "x"

Answer 10

I also forgot to add I have to make the problem not a fraction and then solve it

Answer 11

and thats what I didn't understand

Answer 12

so why don't you try to do what I asked ?

you have nearly done it . I told oyu where the mistake is so try again

5(x/5+8) =?

Answer 13

is it just x/5 + 40 or x/25 +40 or x/25 +8 because im confused

Answer 14

ohhh... I see...you'd want to get rid of the denominator
well... let's look at all 3 denomiators there
5 * 1 * 4 = 20
so let us multiply all by 20 then

so we get \(\bf \cfrac{ x }{ 5 }+8=\cfrac{ 3 }{ 4 }\implies \cfrac{ x }{ 5 }+\cfrac{8}{1}=\cfrac{ 3 }{ 4 }\implies {\color{brown}{ \cancel{ 20 }}}\cfrac{ x }{ \cancel{ 5 } }+{\color{brown}{ 20}}\cfrac{8}{1}={\color{brown}{ \cancel{ 20 }}}\cfrac{ 3 }{ \cancel{ 4 } }\implies ?\)

Answer 15

im 7th grade so this is a little hard to understand

Answer 16

It's none of yourt previous answers

Forget the 8 for a minute
what is 5(x/5) (in words that is 5 times x divided by 5)

Answer 17

hmmm at 7th grade... I'd think fractions should have been covered very well by now

Answer 18

i get distracted by little things easily and the teacher confuses me at some times

Answer 19

all these excuses are not getting you anywhere - are oyu going to try this - or are oyu waiting for the answer?

Answer 20

i am trying i really am confused and this is just an example of all the rest of my math hw that i have to do so im also in a hurry.

Answer 21

FallinLeaf may well be, unfortunately, that still doesn't exempt you from studying the material, or try many great tutorials online

Answer 22

im am trying

Answer 23

you cannot hurry something that oyu don't know how to do

in the original equation ther is x/5

so - to get rid of that we multiply the whole equation by 5

you NEARLY did it in your FIRST reply

go back and do it again

you were nearly correct

Answer 24

\(\bf \bf \cfrac{ x }{ 5 }+8=\cfrac{ 3 }{ 4 }\implies \cfrac{ x }{ 5 }+\cfrac{8}{1}=\cfrac{ 3 }{ 4 }\implies {\color{brown}{ \cancel{ 20 }}}\cfrac{ x }{ \cancel{ 5 } }+{\color{brown}{ 20}}\cfrac{8}{1}={\color{brown}{ \cancel{ 20 }}}\cfrac{ 3 }{ \cancel{ 4 } }\implies ?\)

would give you a plain linear equation with no denominators

Answer 25

i have good grades but i just don't get this for some reason, and im not good at fractions no matter how hard i try

Answer 26

so what do you want?

Answer 27

I have asked oyu 3 times to do something to correct your mistske, but all oyuve done is complain
how do you want to solve this?

Answer 28

im trying ok and ive been trying to answer you ok is it x/5 +40?

Answer 29

4/20 + 40/20 ? this is just how i think the teacher wanted it so im just asking

Answer 30

and I already told you that it is not that

there are 3 terms in the equation:

x/5
8
15/20

multiply each of them by 5 and write the answer here

x/5 *5=
8 *5=
15/20 *5 =

Answer 31

sorry - my error - the three terms are below:
multiply each of them by 5 and write the answer here

x/5 *5=
8 *5=
3/4 *5 =

Answer 32

5/25
40
15/20

Answer 33

when you multiply a fraction by a number you only multiply the TOP number

I'm sorry - you seem to be a very long way from being ready to do this type of question.

I suggest you revise your fractions multiplying and using LCD to combine fractions. You need to be able to do these things before you can do the whole of this question.

I will give you the step I was leading to:

5(x/5+8) = x+40

5(3/4) = 15/4

Please look at your text or ask your teacher again - you need some background study before you are ready to complete this homework

Answer 34

Giving you the answer is no use to you at all

If you want to learn - you have to study and DO the work

Do what oyu have to - I will not give you the answer

Answer 35

sorry but im just tired and i will do what you said thank you a lot

Answer 36

bye i have to go
