1:0,25 0,6:0,15

To convert the decimal numbers to fractions, we can follow these steps:

1. Identify the place value of the last digit after the decimal point. In the first number, 0.25, the last digit is in the hundredth place (2/100). In the second number, 0.6, the last digit is in the tenths place (6/10).
2. Simplify the fraction, if possible. In the first number, 2/100 can be simplified to 1/50. In the second number, 6/10 can be simplified to 3/5.

Therefore, the fractions equivalent to the given decimals are:

0.25 = 1/50 0.6 = 3/5
