1. 1 3/4 – 1,25 =

Penjelasan dengan langkah-langkah:

1. 1 3/4 – 1,25 = 7/4 – 1,25

= 1,75 – 1,25 = 0,5

2. 2,275 – 2/5 = 2,275 – 0,4

= 1,875

3. 4,5 – 2 1/8 = 4,5 – 17/8

= 4,5 – 2,125 = 2,375

4. 5 1/5 – 1/2 = 26/5 – 1/2

= 26×2/5x2 – 1×5/2x5

= 52/10/5/10

= 57/10

5. 4,59 – 2 1/5 = 4,59 – 11/5

= 4,59 – 2,2 = 2,39

6. 4 5/8 – 3,875 = 37/8 – 3,875

= 4,625 – 3,875 = 0,75

7. 4 1/10 – 2/5 = 41/10 – 2×2/5x2

= 41/10 – 4/10

= 37/10

8. 5,44 – 2 1/8 = 5,44 – 17/8

= 5,44 – 2,125

= 3,315

9. 4 7/10 – 3,77 = 47/10 – 3,77

= 4,7 – 3,77 = 0,93

10. 2 1/4 – 0,75 = 9/4 – 0,75

= 2,25 – 0,75 = 1,5
