Answer 5

you need to change both fractions to a common denominator to do addition (and subtraction). What is the least common multiple of 6 and 8?

Answer 6

do you mean LCD or LCM cause its been saying LCD

Answer 7

for this purpose, they're pretty much the same thing

Answer 8

oh ok, i thought so

Answer 9

So the LCD of 6 and 8 is 24?

Answer 10

right

Answer 11

hi

Answer 12

stop saying hi plz.

Answer 13

so now you have to multiply the fractions by 1 in other forms to change them.
multiply 1/6 by 4/4 and mulitply 3/8 by 3/3.\[\frac{ 1\times4 }{ 6\times4 }+\frac{ 3\times3 }{ 8\times3 }\]

Answer 14

that will give you 24 in both denominators

Answer 15

1*4=4 & 3*3=9

Answer 16

yes, so you have
4/24 + 9/24 =

Answer 17

Now I add the numerators together?

Answer 18

yes

Answer 19

so 4+9=13

Answer 20

right

Answer 21

so your final answer is what?

Answer 22

13/24 ?

Answer 23

yep :)

Answer 24

TY for the help @peachpi !!! :D

Answer 25

you're welcome

Answer 26

the reason this works is because once the two values are expressed with a common denominator, that fraction can be factored out. it leaves a simple addition of whole numbers which can be added and then multipled by the factor to yield a single value:
\[\frac{ 1 }{ 6 }+\frac{ 3 }{ 8 }=\frac{ 1 }{ 6 }\cdot \frac{ 4 }{ 4 }+\frac{ 3 }{ 8 }\cdot \frac{ 3 }{ 3 }=\frac{ 4 }{ 24}+\frac{ 9 }{ 24 }=\frac{ 1 }{ 24 }\left( 4+9 \right)=\frac{ 1 }{ 24 }\left( 13 \right)=\frac{ 13 }{ 24 }\]

Answer 27

can you help with another cause im still kinda not used to it. :/
