10) Verify that (a+b)+c.=a+(b+c) by taking (1) a = -2 , b = -2/3 , c = -3/4 (2) a = -12, b = -9/11, c = 7/-12 11) Simplify the following: 1) (2/3) + (-4/5) + I + (-2/3) + (-11/5) 2)(5/8) + (-8/9) + 0 + (-13/3) + (17/24) 12) Subtract : 1) (-3/4) from (1/2) 2) (5/8) from (-3/14) 13) What should be added to (-7/20) to get (-2/5)? 14) The sum of two rational numbers is (-3/7). If one of the number is (-5/8) find the other. 15) The sum of two rational numbers is (-5/8). If one of the number is (6/11), find the other number.
