1. a. -44
b. 3, 0, -8, -30, -44
c. 36, 23, 21, 3, 0, -8, -30, -44

2. a. 20 - 27 x (-2) = 20 - (-54) = 20 + 54 = 74
b. (-75) ÷ 5+ (-43) = -15 - 43 = -58
c. -108 ÷ (-4) + 9 x (-5) = 27 + (-45) = 27-45 = -18

3. -6°C + (2°C/5mnt x 30mnt)
= -6°C + 12°C
= 6°C

4. a. ¼ = ¼ x 100% = 25%
b. 1 7/20 = 27/20 x 100% = 135%
c. 0,38 = 0,38 x 100% = 38%
d. 1,4 = 1,4 x 100% = 140%
