x/2 + x/4 = 1

the answer is 1 1/3

can you show me the method please

thanks in advance :)

  • 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,
    wasn't Rachel's answer 1/3
    and mine was 1 1/3 ??
