Tolong dong bantuin dan tolong dikerjainnya yang benar ya

1) 1/2 = (1×5)/(2×5) = 5/10 = 0,5
2) 1/5 = (1×2)/(5×2) = 2/10 = 0,2
3) 2/5 = (2×2)/(5×2) = 4/10 = 0,4
4) 1/4 = (1×25)/(4×25) = 25/100 = 0,25
5) 3/6 = (3:3)/(6:3) = 1/2 = (1×5)/(2×5) = 5/10 = 0,5
6) 3/5 = (3×2)/(5×2) = 6/10 = 0,6
7) 3/25 = (3×4)/(25×4) = 12/100 = 0,12
8) 7/25 = (7×4)/(25×4) = 28/100 = 0,28
9) 11/25 = (11×4)/(25×4) = 44/100 = 0,44
10) 12/25 = (12×4)/(25×4) = 48/100 = 0,48
