9/10,2/5,5/4,49/140

Answer 1

9/10 = x/100
x = 9*100/10
x = 900/10
x = 90
deci 9/10 = 90/100 sau 9/10 = 90%

2/5 = x/100
x = 2*100/5
x = 200/5
x = 40
2/5 = 40/100 sau 2/5 = 40%

5/4 = x/100
x = 5*100/4
x = 500/4
x = 125
5/4 = 125/100  sau 5/4 = 125%

49/140=x/100
x = 49*100/140
x = 4900/140
x = 35
49/140 = 35/100 sau 49/140 = 35%
