Tolong dikumpulkan besok tolong bantu, caranya kayak di atas nya soalnya gak ngerti

1. 2/5 = 2/5 x 2/2 = 4/10 = 0,4
2. 3/4 = 3/4 x 25/25 = 75/100 = 0,75
3. 8/25 = 8/25 x 4/4 = 32/100 = 0,32
4. 7/20 = 7/20 x 5/5 = 35/100 = 0,35
5. 27/250 = 27/250 x 4/4 = 108/1000 = 0,108
6. 3/8 = 3/8 x 125/125 = 375/1000 = 0,375
7. 5/2 = 5/2 x 5/5 = 25/10 = 2,5
8. 4 1/2 = 9/2 = 9/2 x 5/5 = 45/10 = 4,5
9. 3 1/4 = 13/4 = 13/4 x 25/25 = 325/100 = 3,25
10. 5 3/50 = 253/50 x 2/2 = 506/100 = 5,06
