Pembahasan;

1. 20 2/3 × 3/4 - 25%
= 62/3 × 3/4 - 25/100
= 186/12 - 25/100
= 9300/600 - 150/600
= 9150/600
= 1525/100
= 305/20
= 61/4
= 15 1/4

2. 4 2/3 : 3 1/2
= 14/3 : 7/2
= 14/3 × 2/7
= 28/21
= 4/3
= 1 1/3

3. 3/4 : 2 5/6
= 3/4 : 17/6
= 3/4 × 6/17
= 18/68
= 9/34

4. 6,93 - 4,12 + 25%
= 693/100 - 412/100 + 25/100
= 281/100 + 25/100
= 306/100
= 153/50
= 3 3/50

5. 0,64 × 3/8 : 125%
= 64/100 × 3/8 : 125/100
= 192/800 : 125/100
= 192/800 × 100/125
= 19200/100000
= 3840/20000
= 960/5000
= 192/1000
= 48/250
= 24/125
