Divide by the number of parts in the ratio.
Imagine sharing sweets between person A and person B in the ratio 2:3.
As a proportion Person A would receive 2/5ths (40%) of the sweets and B would receive 3/5ths (60%) of the sweets.
You need ratios to find out what scale to use.
Well, I know one career that uses proportions. Being a baker, for example scaling a recipe up and down depending on the number of guests you have.
Convert them to fractions.
That's a lot like asking "How do you do a bicycle ?"Probably the most important step ... the one that must always be done first, andthe one that you haven't completed yet ... is to be sure you know and understandexactly what it is that you need to 'do' with the ratios or proportions that are beingdiscussed.
Related concepts to fractions include ratios, proportions, percents, decimals, probabilities, cents, division, inverses. Parts of fractions are numerator and denominator. Fractions greater than 1 are improper fractions or mixed numbers.

I'm sure they use ratios and proportions at many different points in the practice of their profession. One obvious application is in construction of exact scale models of aircraft and their components for wind-tunnel tests.
Ratios ARE numerical.

The law of multiple proportions states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers. Two examples of the law of multiple proportions are carbon monoxide, CO, and carbon dioxide, CO2, and water, H2O, and hydrogen peroxide, H2O2.
Rates are ratios ... Speed is a rate of distance per unit of time... ratio of distance to time. Proportions are two equal ratios, whether they are rates or not.
You use ratios or proportions for making sure you use the correct amount of each ingredient.
