Posted by on .

So I have figured this out but I don't think this is the way I am suppose to write the equation fraction out.

8 1/2 years ago, Steven was 7 years old. How old is he now?

Do I write it out like this 8/1 + 1/2 + 7/1 ??? But it comes out too high of a number. I know I am doing it wrong. 8 1/2 + 7 = 15 1 /2 this is right. But can't be this easy. I am doing fractions adding and subtracting right now. Do I write it out f - 7 = 8 1/2 and f = 15 1/2 formula???

  • Fraction - ,

    Is it f - 7 = 15 1/ 2 formula ?

  • Fraction - ,

    This is correct.

    8 1/2 + 7 = 15 1 /2

  • Fraction right?? - ,

    I know what is it! Is it f- 7 = 8 1/2

    which equal 15 1/2

    right ?? :)

  • Fraction - ,

    Yes, that's right.

  • Fraction This right? - ,

    But don't I in one step 17/2 + 7/1 find LCD? which is 2 ??

  • Fraction - ,

    Thank you.

  • Fraction - ,

    If you must change these numbers to fractions, then >>

    8 1/2 = 17/2

    f - (14/2) = (17/2)

    f = (17/2) + (14/2)

    f = 31/2 = 15 1/2
