    when you add fractions, the denominators must be the same. You do NOT add the denominators

    yeah you have to get all the denominators to be the same number

    I drew above how to convert to rational exponent form

    from there you just add 1/2 to 1/4 to get 3/4

  29. jim_thompson5910

    since 1/2 is the same as 2/4, that's why I got 2/4 + 1/4 = 3/4
