wat is the least common denominator of 5/12 and 7/18

- RagingSquirrel

do you want an explanation or just an answer?

- anonymous

36

- anonymous

just the answer? 36?

- anonymous

to figure this out we should find a common divisor. to do this, we should multiply the left fraction by 1 in the form of the divisor of the right fraction and the right fraction by 1 in the form of the divisor of the left fraction. Sounds wordy but its like this:
\[\frac{12}{12}\times\frac{7}{9}-\frac{9}{9}\times\frac{5}{12}\]after this we have everything in terms of the same base, and we can write it like this: \[\frac{84-45}{108}=\frac{39}{108}\]which reduces down to 13/36

yeah it's the lowest number that is divisible b both 18 and 12

- RagingSquirrel

haha... i knew junkie was typing up something big

- anonymous

It's what I do :)

change to a mix number 145/14

- RagingSquirrel

you sure you dont want me to explain?

- anonymous

14 5/14

- anonymous

10 5/14*

- anonymous

which answer?

- anonymous

the second

lol i was like...
whaaa?

7 and 1/5 divided by 1 and 1/5

- anonymous

yes just checking my answers

- RagingSquirrel

6.

- anonymous

is that the answer 6

- RagingSquirrel

yeah.

- anonymous

36/5//6/5
=6

- RagingSquirrel

hey, dont forget to click "good answer". It would really help me out.

- anonymous

same

- RagingSquirrel

Thanks! Leveled up to 16.

- anonymous

thanks

- anonymous

ok now i have another

- RagingSquirrel

shoot

evaluate using the correct order of operations for 1/4 3/8 and 5/6

- anonymous

sorry im not too good with math

- anonymous

are you supposed to add them?

- anonymous

it just says evaluate using the correct order of operations

- RagingSquirrel

order of operations can be abbreviated PEMDAs. In 5th grade i didnt think it would help that much, but it did.
Parentheses
Equations
Multiplication
Division
Addition

- anonymous

my bad i gave u the wrong one

- anonymous

ahaha..

- anonymous

its find the least common denominator

- anonymous

24

- anonymous

the lowest number divisible by 4 6 and 8 is 24

- RagingSquirrel

that....
makes sense

- anonymous

ok now wat is 7/8 divided by 5/11

- RagingSquirrel

one sec.

- RagingSquirrel

1 37/40

- anonymous

how did u get that?

- anonymous

i could be wrong, but this is what i got. (
7 / 9) - (5 / 12) = 0.361111111

- RagingSquirrel

turn the second numbers around. then you simply multiply

- anonymous

woah
hold on here i can do that

- RagingSquirrel

Ice, she asked for division.

- anonymous

7/8//5/11=7/8*11/5=77/40

- anonymous

what is 18 and 6/7 minus 13 and 13/14

- RagingSquirrel

- anonymous

oh. nevermind. My bad. I misread.

- anonymous

omg thank you so much!!!!!!

- RagingSquirrel

Haha, google is my friend.

- anonymous

i tried lookifind anyng for so many i couldnt

- anonymous

i tried looking i couldnt find any

- anonymous

i need help with one more

- RagingSquirrel

okay.
take your time.

- anonymous

[ 1/2+ 1/3)\times7/5

- RagingSquirrel

remember. PEDMAS.

- anonymous

i got confused with this one

- RagingSquirrel

This is order of operations.

- RagingSquirrel

Parentheses
Equations
Multiplication
Division
Addition

- RagingSquirrel

the ( ) s are parentheses. So we handle them first.

- RagingSquirrel

1/2 + 1/3 = 5/6. So we can simplify down to 5/6 times 7/5

- RagingSquirrel

Theres no equations, so we go to multiplication.

- RagingSquirrel

5/6 Times 7/5 is 2 and 7/30. So theres your answer.
2 7/30

- anonymous

reduce 14 1/24
