x/2 + x/4 = 1

can you show me the method please

• Maths -

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

• Maths -

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

• Maths -

The book states that the answer is one and a third

i got the same answer as Rachel

• Maths -

Ummmh,
and mine was 1 1/3 ??
