= 3/5 × 6/1
= 18/5
= 3 3/5
2. 0,8 × 19% × 2 2/8
= 8/10 × 19/100 × 18/8
= 1/10 × 19/100 × 18/1
= 342/1000
= 0,342
3. 1,2 : 0,4 : 15/25
= 12/10 × 10/4 × 25/15
= 3000/600
= 5
4. 7 2/8 - 3 5/9 + 1 1/4
= 58/8 - 32/9 + 5/4
= 29/4 - 32/9 + 5/4
= 261/36 - 128/36 + 45/36
= 178/36
= 89/18
= 4 17/18
5. 4 2/5 + 1,2 : 2 2/5
= 22/5 + 12/10 × 5/12
