I need help answering this fractions for math class

SELF-TEST 3 Reducing Fractions Chapter 1 - ARITHMETIC NEEDED FOR DOSAGE MATH 1 Intro to Reduce these fractions to their lowest terms. Answers are given at the end of the chapter. Fractions 24 36 216 4. 70 490 10 . 68 Adding Fractions If you need to add two fractions that have the same denominator, first add the two numerators; write that sum over the denominator and, if necessary, reduce. If the two fractions have different denominators, the process takes two steps. First convert each fraction, multiplying both of its numbers by their lowest common denominator. After you've convert- ed both fractions, add their two numerators together. If necessary, reduce. 8 ( X3 ) 5 ( x3 ) = 15 = 6 2 (X5) 3 ( x5 ) = 18 = 3 15 + 19 = 15 or 145 Subtracting Fractions To subtract two fractions that have the same denominator, first subtract their numerators and then write the difference over the denominator. Reduce if necessary. 32 - 32 = 32 If the two fractions have different denominators, first convert each fraction using the lowest com- mon denominator (just as you did in the adding example above). Then subtract the numerators, and reduce again if necessary. 3 - 3 7 ( X3 ) +8 (X3 = 24 = 35 2 (x8) 3 ( X8) = 24 = 3 24 - 19 = 24
