Most of the ones I can't figure out I'm just going to ask my instructor when we go back to class tomorrow. However, there's one where I got the right numbers, but I'm saying positive, and the answer says negative. x + 1/2 = 1/8 To find the answer, all I need to do is 1/2 - 1/8 (or vice-versa if the problem were subtraction), which gets me 3/8. Therefore, 3/8 + 1/2 = 1/8. They have it as -3/8, though, and I don't understand where they're getting the negative answer from. There weren't any negative equations in the problem. I'm on Chapter 3, Section 9: Solving Equations with Fractions.
That would explain their negative answer. I thought fractions work differently than normal equations, though. For example, after solving an equation, a fraction with lower numbers could be higher than a fraction with higher numbers. Okay, so if I did it the other way around, it would be 1/8 - 1/2. The LCP of them is 8; therefore, it becomes 1/8 - 4/8, which would get me -3/8. Thanks, Machina! Edit - 8:25 PM PT: Never mind that second paragraph. I was confused. It's the answer minus whatever to do that.
