tolong di bantu aku pissssss

1. 92,5 x 4,5 = 416,25
2. 9,25 : 1 1/2 = 925/100 : 3/2 = 925/100 x 2/3 = 2775/300 = 37/6
3. 4,5 + 2 1/4 = 4,5 + 9/4 = 4,5 + 225/100 = 4,5 + 2,25 = 6,75
4. 4,5 x 20% = 45/10 x 20/100 = 900/1000 = 9/10 atau 0.9 atau 90%
5. 400 x 10% = 400 x 10/100 = 4000 : 100 = 40
6. 40 x 3/4 = 120 : 4 = 30
7. 100 x 1 1/2 = 100 x 3/2 = 300 : 2 = 150
8. 4,2 : 0,6 = 7
9. 100 x 25% = 100 x 25/100 = 2500 : 100 = 25
10. 25% + 1 1/2 + 3,25 + 2/5 = 25/100 + 3/2 + 325/100 + 2/5 = 25/100 + 150/100 + 325/100 + 40/100 = 540/100 = 27/5

Maaf Kalau Salah :)
