30 is the LCD

in order to get this you have to multiply each denominator until you see a match

OpenStudy (anonymous):

for example....

OpenStudy (anonymous):

30m is LCD

OpenStudy (anonymous):

you have 2 and 3

OpenStudy (anonymous):

to find the LCD

OpenStudy (anonymous):

you have to do 2,4,6,8,10,12,14,16,18.... Then you do 3,6,9,12,15,18,...... The LCD is the first common number

OpenStudy (anonymous):

If you wanted to right them as equivalent fractions with the LCD: 9/30 , -8/30

OpenStudy (anonymous):

the first common number is 6 so 6 is the lcd
