58% : 45 % =

To simplify the ratio \(58\% : 45\%\), you can divide both percentages by 45.

First, convert the percentages to decimals:

• \(58\% = 0.58\)
• \(45\% = 0.45\)

Now, divide \(0.58\) by \(0.45\):

\[ \frac{0.58}{0.45} \approx 1.2889 \]

So, the ratio in decimal form is approximately \(1.29\).

Now, if you want to express this ratio as a fraction, you can write it as:

\[ \frac{58}{45} \]

This fraction can be simplified further if needed, but since 58 and 45 have no common factors (beyond 1), the simplest form is:

\[ \frac{58}{45} \]

Thus, the ratio \(58\% : 45\%\) can be expressed as \(58 : 45\) or approximately as \(1.29 : 1\).
