Answer 1

a) 2,4 - 1/2 =19/10

b) 1,5 + 1/4 =7/4

c) 0,9 - 7/12 =19/60

d) 2 1/2 + 0,6 =31/10

e) 2,3 - 1 1/2 =4/5

f) 0,8 + 2/3 =22/5

Answer 2

a) 2,4 - 1/2 = 2,4 - 0,5 = 1,9 b) 1,5 + 1/4 = 1,5 + 0,25 = 1,75 c) 0,9 - 7/12 = 0,9 - 0,5833 (approximately) = 0,3167 (approximately) d) 2 1/2 + 0,6 = 2,5 + 0,6 = 3,1 e) 2,3 - 1 1/2 = 2,3 - 1,5 = 0,8 f) 0,8 + 2/3 = 0,8 + 0,6667 (approximately) = 1,4667 (approximately)

So the solutions are: a) 1.9 b) 1.75 c) 0.3167 (approximately) d) 3.1 e) 0.8 f) 1.4667 (approximately)
