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.
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.
Oh, ratios and proportions are like little friends that help us in so many careers! You might find them at play in fields like finance, cooking, engineering, and even art. Embracing these mathematical tools can open up a world of possibilities where you can create beauty and balance in your work. Just remember, there's no mistakes, only happy little accidents along the way.
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 can be partly explained by the idea that whole atoms of the same element combined to form compounds. Examples of the law of multiple proportions are CO and CO2.
you can use scale model to measure proportions
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.
Compounds always contain elements in exact ratios, based on the chemical formula of the compound. This means that the elements are present in specific and consistent proportions in the compound.
