Jawaban:

1. 2 x 4 3/8 – 5 3/4 = 2 x 35/8 – 23/4 = 2 x 35/8 –

46/8 = 2 x 11/8 = 22/8 = 11/4 = 2 3/4

2. 1,25 – 0,5 x 1/4 = 125/100 – 5/10 x 1/4 =

125/100 – 50/100 x 1/4 = 75/100 x 1/4 = 3/4 x 1/4

= 3/16

3. 1/4 + 1,5 : 0,25 = 1/4 + 15/10 x 100/25 = 10/40 +

60/40 x 100/25 =70/40 x 100/25 = 7.000/1000

= 7

4. 2 4/5 x 1/8 – 0,15 = 14/5 x 1/8 – 15/100 = 14/5 x

100/800 – 120/800 = 14/5 x (-20/800) =

-280/4.000 = -0,07

5. 14,1 : (1 3/5 + 75%) = 141/10 : ( 8/5 + 75/100) =

141/10 : (800/500 + 375/500) = 141/10 x

500/1.175 = 7.050/1.175 = 6
