A) 2 i 1/2 + 3 i 5/8 = 2 i 4/8 + 3 i 5/8 = 5 i 9/8 = 6 i 1/8 b) 11 i 1/3 - 2 i 2/5 = 11 i 5/15 - 2 i 6/15 = 10 i 20/15 - 2 i 6/15 = 8 i 14/15 c) 3/7 * 1 i 1/2 = 3/7 * 3/2 = 9/14 d) 2 i 1/5 * 2 i 1/3 = 11/5 * 7/3 = 77/15 = 5 i 2/15
b) 11 i 1/3 - 2 i 2/5 = 11 i 5/15 - 2 i 6/15 = 10 i 20/15 - 2 i 6/15 = 8 i 14/15
c) 3/7 * 1 i 1/2 = 3/7 * 3/2 = 9/14
d) 2 i 1/5 * 2 i 1/3 = 11/5 * 7/3 = 77/15 = 5 i 2/15
