okay so im studying for a college placement test because i plan on going back to college this fall, since ive been out for 5 years i have to retake the placement test.
my weakness is algebra- fractions, decimals, mixing numbers & letters together- LOL!
so when you have a problem like: 3 1/2 + 4 2/3 are you suppose to find a common denominator? or do you simply add 3 +4 and add the numerators and denominators? or do you multiply the whole number and the denominator, then add the numerator so you get 7/2 + 14/3, then find a common denominator?
ugh, so confusing... i wish i could skip over the math portion altogether. im not asking for the answer, just HOW to find the answer.
