How to determine the value of a ratio?

A ratio is a comparison of two quantities. It is used to show the relationship between those quantities. Ratios can be expressed in multiple ways, such as as a fraction, with a colon, or as a decimal. Determining the value of a ratio involves comparing the quantities being compared and expressing the ratio in the simplest form.

To determine the value of a ratio, you need to first identify the two quantities being compared. Once you have identified those quantities, you can express the ratio in the simplest form by dividing both quantities by their greatest common factor. This will give you the actual value of the ratio, which can be expressed as a fraction or a decimal.

Here are some FAQs related to determining the value of a ratio:

1. What is a ratio?
