particularly in jobs

Answer 1

Bankers and accountants use ratios all the time: expense ration, turnover ration, debt/asset ratio, price/earnings ratio etc.
Artistic types use ratios to mix secondary and tertiary colors from primary colors, also the human body has certain ratios so when drawn, the bodies look in correct proportion if done to proper ratio.
Great chefs work with recipes containing ratios such as teaspoon of one ingredient per cup of another.
Doctors, of course are always calculating ratios as they determine medications. So many mg of meds per 10 pounds etc.

Answer 2

Ratios In Real Life

Answer 3

A couple of easy examples would be. Mixing fuel for weed-eaters and other small 2cycle devices that are designed to run on a gas and oil mixture. If the engine requires a ratio of 4 to 1 for example then you would mix 4 ounces of oil to 1 gallon of gas.

Currency exchange rates are the other example.
1 US dollar may be exchanged for 3 franks as an example. The ratio would then be 3 to 1.

Answer 4

''ratio'' is used for many purposes.

Examples:

1) density = mass/volume => Physics

2) i.q = (mental age/ real age) X 100 => Psychology

3) brain's weight = (2/100) X normal weight => Biology

4) circle's radius = circle' perimeter/ 2 pi =>Mathematics

5) For Yogi Berra( a Hall of Fame baseball
player) Baseball is 90% mental - the other
half is physical =>Baseball

6) The ratio of hydrogen atoms to oxygen
in water(H2O) is 2:1 => Chemistry

7)The ratio of the mass of Jupiter to the
mass of the Earth is approximately 318:1 => Astronomy

Answer 7

Ratios are used in all kinds of ways such as currency exchanges, (1.25 for every euro for example). Supermarket math (whether you know it or not) is all about ratios. 3 dollars for every chicken, you want three chickens. so you solve the equation $3/(1 chicken) = $x/(3 chicekns)
