Use the commutative property to simplify the expression. 2/5+1/6+3/5 A. 1/30(12+5 + 18) = 1/30 (35) = 35/30= 1 1/6
B. 2/5 + 3/5 = 1 + 1/6= 1 1/6
C. (2/5+1/6) +3/5 = 17/30 + 18/30 = 35/35 = 1 1/6
D. 2/5+ (1/6 + 3/5) = 2/5 + 23/30 = 35/30 = 1 1/6

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
