The most general way to convert any fraction to a decimal is to perform the division. Divide 16 by 25.

16.0/25 = .6 remainder 1.0

1.00/25 = .04 remainder 0

.6 + .04 = .64

For fractions whose denominators have only 2 or 5 as factors, you can convert to decimal by expressing the fraction over a power of 10. Then, use place value to locate the decimal point.

16/25 = (16/25)*(4/4) = (16*4)/(25*4) = 64/100 = 0.64

16.0/25 = .6 remainder 1.0

1.00/25 = .04 remainder 0

.6 + .04 = .64

For fractions whose denominators have only 2 or 5 as factors, you can convert to decimal by expressing the fraction over a power of 10. Then, use place value to locate the decimal point.

16/25 = (16/25)*(4/4) = (16*4)/(25*4) = 64/100 = 0.64
