eclipsedstar (eclipsedstar):

Spam. Spam. Green eggs and spam.

OpenStudy (alexandervonhumboldt2):

everyone is a mthlet

OpenStudy (anonymous):

\[(\frac{ 3 }{ 5}-\frac{ 1 }{ 2 })*\frac{ 3 }{ 8}\] @sammixboo

OpenStudy (arabpride):

E Z

sammixboo (sammixboo):

First do what is in the parenthesis

OpenStudy (alexandervonhumboldt2):

first make the denominator the same in the brasket

sammixboo (sammixboo):

3/5 - 1/2 We have to make them have the same denominators

sammixboo (sammixboo):

So that means we have to find the LCD which is Lowest Common Denominator. To find this, find the multiples of 5 and 2

OpenStudy (anonymous):

so ugh tell me im lost

sammixboo (sammixboo):

Then after you find some of the multiples of 5 and 2, which are Multiples of 5 - 5, 10, 15, 20... Multiples of 2 - 2, 4, 6, 8, 10, 12... You find the lowest number they have in common

OpenStudy (anonymous):

10

OpenStudy (alexandervonhumboldt2):

yes

sammixboo (sammixboo):

So look at this Multiples of 5 - 5, 10, 15, 20... Multiples of 2 - 2, 4, 6, 8, 10, 12... What number is the lowest number that are both in the Multiples of 5 and 2

OpenStudy (alexandervonhumboldt2):

correct

OpenStudy (anonymous):

oka so what else im in need of help @AlexandervonHumboldt2

sammixboo (sammixboo):

Right, so that means we multiply 3/5 by 2 and 1/2 by 5 So what is \(\dfrac{3*2}{5*2}\) And what is \(\dfrac{1*5}{2*5}\)

OpenStudy (alexandervonhumboldt2):

now multiply first fraction by 2/2 and second fraction by 5/5

sammixboo (sammixboo):

Sorry, multiply the numerator and denominator of 3/5 by 2 and the numerator and denominator of 1/2 by 5.

OpenStudy (anonymous):

so its going to be 6/10 and 5/10 @AlexandervonHumboldt2

OpenStudy (alexandervonhumboldt2):

just now subtract 6/10-5/10=????

OpenStudy (alexandervonhumboldt2):

yes

sammixboo (sammixboo):

6/10 - 5/10 is the same as \(\dfrac{6-5}{10}\)

OpenStudy (anonymous):

so its 1/10 @sammixboo @AlexandervonHumboldt2

OpenStudy (alexandervonhumboldt2):

yes

OpenStudy (alexandervonhumboldt2):

now multiply 1/10*3/8=(1*3)/(10*8)

OpenStudy (anonymous):

3/80 wait is this the answer @AlexandervonHumboldt2

OpenStudy (alexandervonhumboldt2):

yes that fraction cannot be reduced so 3/80

OpenStudy (alexandervonhumboldt2):

3/80 is correct
