Please help me. What is the answer to this math problem? Answer: 0 and -1, respectively. Step-by-step explanation: To add or subtract fractions, they must be similar where the denominators are the same. If not, convert to similar terms by finding their least common denominators (LCD): 1) (+1/2) + (+2/3) + (-1 1/6) ⇒ LCD: 6 Divide the LCD by the denominator of each term, then multiply the result by the numerator to determine the equivalent fraction: +3/6 + 4/6 - 7/6 = (3+4-7)/6 = 0/6 = 0 When the numerator is 0, the result is always 0. 2) - (+1/2) + (+2/3) + (-1 1/6) = -3/6 + 4/6 - 7/6 = (-3 + 4-7)/6 = -6/6 ⇒ when dividing integers with unlike sign, the result is positive. = -1
