Jawab:
1.
3 1/4 + 4 3/4 + 25%
= 13/4 + 19/4 + 25/100
= 13/4 + 19/4 + 1/4
= 33/4 → 8 1/4 → 8,25 → 825%

2.
2 1/5 + 3/10 + 30%
= 11/5 + 3/10 + 30/100
= 22/10 + 3/10 + 3/10
= 28/10
= 14/5 → 2 4/5 → 2,8 → 280%

3.
3 3/4 + 0,25 × 1/2
= 15/4 + 25/100 × 1/2
= 15/4 + 1/4 × 1/2
= 15/4 + 1/8
= 30/8 + 1/8
= 31/8 → 3 7/8 → 3,875 → 387,5%

4.
22,08 + 4,12 - 9,25
= 26,2 - 9,25
= 16,95 → 339/20 → 16 19/20 → 1.695%
