I have a question, how would I get the scale for these measurements?

105 x 15
27 x 17
72 x 38

To get the scale for these measurements, you need to calculate the ratio between the measurements and simplify it.

Let's take the first measurement: 105 x 15.
To find the scale, you need to divide both numbers by their greatest common divisor (GCD). The GCD of 105 and 15 is 15.
Dividing both numbers by 15 gives us: 105/15 = 7 and 15/15 = 1.
So the scale for the first measurement is 7:1.

Next, let's calculate the scale for the second measurement: 27 x 17.
The GCD of 27 and 17 is 1 (since they are prime numbers).
Dividing both numbers by 1 gives us: 27/1 = 27 and 17/1 = 17.
Therefore, the scale for the second measurement is 27:17.

Finally, let's calculate the scale for the third measurement: 72 x 38.
The GCD of 72 and 38 is 2.
Dividing both numbers by 2 gives us: 72/2 = 36 and 38/2 = 19.
Thus, the scale for the third measurement is 36:19.
