Answer 1

1. Bentuk persennya
= 10/100
= 10%

2. Bentuk desimal dari 7/20
= 7/20 x 5/5
= 35/100
= 0,35 

3. 2 1/3 + 3 1/4 
= 7/3 + 13/4
= 28/12 + 39/12
= 67/12
= 5 7/12

4. 4 3/2 - 2 1/3
= 11/2 - 7/3
= 33/6 - 14/6
= 19/6
= 3 1/6

5. 0,25 + 6,050
= 6,3

6. 5/20 + 1,25
= 25/100 + 1,25
= 0,25 + 1,25
= 1,5

7. 8/9 x 2 1/3
= 8/9 x 7/3
= 56/27
= 2 2/27

8. 28% + 0,5 + 2,5
= 0,28 + 0,5 + 2,5
= 3,28

9. 7 : 2/5 
= 7 x 5/2
= 35/2
= 17 1/2

10. Jarak Sebenarnya
= Skala x Jarak Peta : 100.000
= 1 : 1.000.000 x 5 cm
= 5.000.000 : 100.000
= 50 km
