Question

What is the constant proportional of 1.5 and 3.9

Answer 1

To determine the constant proportion between 1.5 and 3.9, we can divide the two values and see if the result is the same for both.

For example:

1.5 / 3.9 = 0.3846

So, the constant proportion between 1.5 and 3.9 is 0.3846. This means that for every 1.5 units, there are 3.9 units. This relationship can be expressed as a ratio:

1.5 : 3.9 = 0.3846

If we compare this ratio to other pairs of values, we can see if it remains constant. For example, if we multiply both values by the same amount, the ratio should remain unchanged:

(1.5 * 2) / (3.9 * 2) = 3 / 7.8 = 0.3846

So, the ratio remains constant, and the constant proportion between 1.5 and 3.9 is 0.3846

Answer 2

The constant of proportionality is the ratio between two quantities that are in proportion. If two quantities are proportional, their ratio is always the same, and this constant ratio is called the constant of proportionality.

Given the two quantities 1.5 and 3.9, the constant of proportionality can be found by dividing one by the other:

k = 3.9 / 1.5

k = 2.6

So the constant of proportionality between 1.5 and 3.9 is 2.6.
