What is the lowest common multiple between 3 and 15?

OpenStudy (anonymous):

OpenStudy (jhannybean):

It is not 5. 3 = 3, 6, 9, 12, 15 15 = 15 , 30, 45 ....etc

OpenStudy (jhannybean):

15 is the greatest COMMON factor amongst both of these numbers.

OpenStudy (anonymous):

ok well if u add them togather you get 0.932 which as a fraction is 233⁄250

OpenStudy (anonymous):

i think it 233/250

OpenStudy (jhannybean):

So \[\frac{2}{3} \cdot \frac{5}{5} +\frac{4}{15} \]\[= \frac{10}{15} +\frac{4}{15}\]Because they share the same denominator, we can write it as one combined fraction. \[=\frac{10+4}{15} =~?\]

OpenStudy (gelow):

OpenStudy (jhannybean):
