  • 1. 0,125 = 125/100 : 2 = 25/50 : 5 = 5/10 : 5 = 1/2
    2. 3/4 x 25 = 75/100 = 0,75
    4. 9/5 x 4 1/3 = 9/5 x 13/3 = 117/15 : 3 = 39/5 = 7 4/5
    5. 0,25 = 25/100 = 25%
    6. 40/100 : 2 = 20/50 : 2 = 10/25 : 5 = 2/5
    7. 2 1/2 - 1 1/8 = 5/2 - 9/8 = 20/8 - 9/8 = 11/8 = 1 3/8
    8. 6/10 : 1 2/5 = 6/10 x 5/7 = 6/14 : 2 = 3/7
    9. 3/4 + 3/8 - 1/4 = 3/4 + 3/8 = 6/8 + 3/8 = 9/8 - 1/4 = 9/8 - 2/8 = 7/8 
    10. 2 1/2 : 1 3/4 : 1/5 = 2 1/2 : 1 3/4 = 5/2 : 7/4 = 5/2 x 4/7 = 20/14 : 2 = 10/7 = 1 3/7
