How do u turn 13/25 into a decimal

Ulleksa [173]

Best Answer: <span> 3/4 = 0.75
7/50 = 0.14
13/25 = 0.52
17/25 = 0.68
1/20 = 0.05
7/10 = 0.7

To get the decimal you always divide numerator by denominator. So, the process becomes:-
3/4 = 3 ÷ 4 = 0.75
7/50 = 7 ÷ 50 = 0.14
13/25 = 13 ÷ 25 = 0.52
17/25 = 17 ÷ 25 = 0.68
1/20 = 1 ÷ 20 = 0.05
7/10 = 7 ÷ 10 = 0.7 </span>
