Answer 2

It seems like you're providing a series of equations or expressions with two numbers separated by colons, and you want to find the missing values or patterns in these expressions. Let's analyze each of them:

1. 4, 8 : 12 This expression can be interpreted as 4 divided by 8 equals 12 (4/8 = 12), which is not correct.

2. 13, 6 : 16 Similarly, this expression can be interpreted as 13 divided by 6 equals 16 (13/6 = 16), which is not correct.

3. 0, 8 : 20 Again, this expression can be interpreted as 0 divided by 8 equals 20 (0/8 = 20), which is not correct.

It seems there is no consistent pattern or logic in these expressions. The colons are typically used to indicate ratios or proportions, but the given expressions do not follow that convention.

For the second set of expressions:

1. 0.35 : 7 This expression can be interpreted as 0.35 divided by 7 equals 0.05 (0.35/7 = 0.05), which is correct.

2. 0.54 : 9 Similarly, this expression can be interpreted as 0.54 divided by 9 equals 0.06 (0.54/9 = 0.06), which is correct.

3. 0.72 : 4.59 This expression can be interpreted as 0.72 divided by 4.59 equals approximately 0.1567 (0.72/4.59 ≈ 0.1567), which is also correct.

In this case, it appears that the expressions represent divisions where the result on the right side of the colon is the quotient of the division.

Answer 3

It looks like you're providing a series of number pairs and asking for a pattern or relationship between them. Let's analyze the given pairs:

1. 4,8 : 12
2. 13,6 : 16
3. 0,8 : 20

Now, let's try to find a pattern or relationship between these pairs:

1. 4,8 : 12

   • (4 + 8) * 1 = 12

2. 13,6 : 16

   • (13 + 6) * 1 = 19 * 1 = 16 (approximately, not an exact match)

3. 0,8 : 20

   • (0 + 8) * 2.5 = 20

It seems that the relationship between the pairs is not consistent. The first pair follows a pattern where the sum of the two numbers is multiplied by 1, while the third pair has a different pattern where the sum of the two numbers is multiplied by 2.5. The second pair doesn't follow a clear pattern based on the information provided.

Now, let's analyze the additional pairs:

4. 0,35 : 7

   • (0 + 35) * 0.2 = 7

5. 0,54 : 9

   • (0 + 54) * 0.1667 (approximately) = 9 (approximately)

6. 0,72 : 4.59

   • (0 + 72) * 0.06375 (approximately) = 4.59 (approximately)

It appears that for the new pairs, the sum of the two numbers is multiplied by a constant factor that varies from pair to pair. There doesn't seem to be a single consistent pattern for all the pairs, but each pair has its own multiplier.

In summary, the relationship between these pairs is not consistent, and each pair seems to have its own unique pattern where the sum of the two numbers is multiplied by a different constant factor.
