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

To simplify the given ratio of 1:0.25, we need to convert the decimals to a common denominator.

First, we can convert 0.25 to a fraction by dividing 25 by 100:

0.25 = 25/100 = 1/4

Now, the ratio becomes:

1:1/4

To simplify this ratio, we can multiply both sides by 4 to get rid of the fraction:

1 * 4 : (1/4) * 4

4 : 1

Therefore, the simplified ratio is 4:1.

Next, let's simplify the ratio of 0.6:0.15.

To convert 0.6 to a fraction, we divide 6 by 10:

0.6 = 6/10 = 3/5

Similarly, we convert 0.15 to a fraction by dividing 15 by 100:

0.15 = 15/100 = 3/20

Now, the ratio becomes:

3/5 : 3/20

To simplify this ratio, we can find a common denominator. The least common multiple (LCM) of 5 and 20 is 20.

Now, we multiply both sides by the appropriate factors to obtain the common denominator:

(3/5) * 4 : (3/20) * 1

12/20 : 3/20

Therefore, the simplified ratio is 12:3, which can be further simplified by dividing both terms by 3:

4:1.

In summary:

1:0.25 simplifies to 4:1

0.6:0.15 simplifies to 4:1
