x/2 + x/4 = 1
the answer is 1 1/3
can you show me the method please
thanks in advance :)

start by multiplying by the lowest common denominator (in this case 4), simplify, then solve.
4(x/2) + 4(x/4)= 1
4/2=2 and 4/4 =1, therefore:
2x + x = 1
3x = 1
(3x)/3 = 1/3
x= 1/3 
Rachel forgot to multiply the right side by 4, her equation should have been
2x + x = 4
3x = 4
x = 4/3 or 1 1/3 
The book states that the answer is one and a third
i got the same answer as Rachel 
Ummmh,
wasn't Rachel's answer 1/3
and mine was 1 1/3 ??
