A ratio shows us the number of times a number contains another number. The size of unknown scale size will be 1.25.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

As it is given the size of the first row is 1.954, while the size of the second row is 1.563. therefore, the ratio of the first row to the second row will be,

[tex]\rm \dfrac{First\ row}{Second\ row} = \dfrac{1.954}{1.563}\\\\\\\rm \dfrac{First\ row}{Second\ row} =1.25[/tex]

Similarly, if the ratio of the second row and the third row is taken then the size of the third row can be written as,

[tex]\rm \dfrac{Second\ row}{Third\ row} =1.25\\\\\\\rm \dfrac{1.563}{Third\ row} =1.25\\\\\\Third\ row=1.2504 \approx 1.25[/tex]

Similarly, if the ratio of the third row and the fourth row is taken to verify the ratio, we will get,

[tex]\rm \dfrac{Third\ row}{Fourth\ row} = \dfrac{1.25}{1}\\\\\\\rm \dfrac{Third\ row}{Fourth\ row} = 1.25[/tex]

Thus, the size of unknown scale size will be 1.25.
