Question

1/2 + 1/3 + 1/4 =

Answer 1

13/12

Answer 2

hey we have to find te lcm

Answer 3

we have
\[ \frac{1}{2}+\frac{1}{3}+\frac{1}{4}\]
let's find the LCM of 2, 3, 4
2=2
3=3
4=2\(\times\)2
LCM = common factors\(\times\) uncommon factors
2 is the only common
3, and another 2 from 4 are the uncommon factors
LCM=2 \times (2*3)= 12
now rewriting the expression
\[\frac{1\times 6}{2\times 6}+\frac{1\times 4}{3 \times 4}+\frac{1\times 3}{4 \times 3}\]
so we get now
\[\frac{6}{12}+\frac{4}{12}+\frac{3}{12}\]
we get finally
\[\frac{6+4+3}{12}=\frac{13}{12}\]

Answer 4

(6 +4 + 3) /12 =13/12

Answer 5

correct
