Question

5/8+5/12+5/18=

Answer 1

what is the least common multiple of 8,12 and 18?

Answer 2

Look :
58/10+512/100+518/100=580+512+518/100=?

Answer 3

8 = 2*2*2
12 = 2*2*3
18 = 2*3*3
so the least common multiple is
2*2*2*3*3

Answer 4

so we want our denominator to be 72
we can multiply top and bottom of a fraction by the same number and it will still be the same number
so
\[\frac{5}{8}=\frac{45}{72}\]you with me so far?
