sekalian caranya ya thankfull

1. 1/4 x 100 = 25
1 x 25
4 x 25 (supaya bisa jadi 100)
25/100 = 25%

2. 3,123 - 0,9 = 2,223

3. 2/100 x 150.000 = 3000
150.000 - 3000 = 147.000
harganya 147.000

4. 11/3 - 1/2 + 7/6
22/6 - 3/6 + 7/6
19/6 + 7/6 
26/6
4 2/6
4 1/3

5. Nindi : 2
2/2+3 x 40 = 16
apel nindi 16 buah

6. 2/3 x 2/4 : 6/8
4/12 : 6/8
4/12 x 8/6
32/72
8/18
4/9

7. 5,5 - 1/4 - 2 1/5
1/4 = 0,25
2 1/5 = 2,2
0,25 + 2,2 = 2,45
5,5 - 2,45 = 3.05
3.05 m

8. 60 % - 0,35 
60% - 35% = 25 %
25%

9. 4 x 2 1/4
9/4 x 4 = 9
9

10. 200 km : 50 cm
20.000.000 cm : 50 cm 
400.000 cm 
1:400.000

11. 5 x s²
[tex]{ \sqrt[3]{216} } [/tex] = 6
5 x 6 x 6 = 5 x 36 180cm²
180 cm²

12. 2 x 22/7 x 7 x 7 = 154 x 2 = 308
2 x 22/7 x 7 x 20
2 x 22 x 20
2 x 440
880
308 +880 = 1188
1188 cm²

semoga membantu
