Math...Algebra :S

posted by Dawn

Hi, okay um. I'm trying to get his math question (Algebra :o) and i'm not quite sure what i'm doing---but everything i do, i get the wrong answer.
The Question is 2m+n

M= 2/5 and n= 1/2 (Fractions)

Everytime i do the question, i get 9/10 as a answer...but i check the textbook answer and it says that it should be 13/10.

So could somebody please help me *find* the answer. Not give me the answer, but kinda show me it. I donno. Please help somebody!

Thanks a ton.

    Did you forget to multiply 2 * 2/5?

    M= 2/5 and n= 1/2 (Fractions)

    2m+n

    (2 * 2/5) + 1/2

    4/5 + 1/2 = 8/10 + 5/10 = 13/10

    Heh, i just went back and tried it again and figured it out. I was multiplying 2 to both the denominator and numerator. Teehee.

    Thanks anways Ms. Sue :)
