How do I work a problem like this?
5/8 + m = 1

15/8

to get variable 'm' alone, transpose all terms not containing m to the right side of equation,, but remember to reverse the sign:
5/8 + m = 1
m = 1  5/8
*note that the sign of 5/8 becomes negative*
then to subtract fractions, you need to convert 1 to a fraction such that its denominator is equal to 8:
1 = 8/8
now,
m = 8/8  5/8
m = (85)/8 = ?
now, solve for m. :)
