So.. the answer is 4√3

Select all of the scales that are equivalent to 3 cm to 4 km.

ra1l [238]

In mathematics, a scale can be described in charts as a marking system at predefined times, which determines the relationship between the units that are being used and their images on the graph, and the further calculation can be defined as follows:

Since in this question, the ratio is between 3 cm to 4 km you can make a $\bold{\frac{3}{4}=\frac{cm}{km}}$ split, and if you are split between 3 and 4, you get the ratio between $\bold{\frac{\frac{3}{4 \ cm}}{1\ km} = \frac{3\ cm}{ 4\ km}}$ .

$\bold{\to \frac{3 }{ 4}= 0.75}$

Therefore the final answer is "0.75 cm to 1 km"
