Now, we’re going to consider an example of proportional relationship in our everyday life: When we put gas in our car, there is a relationship between the number of gallons of fuel that we put in the tank and the amount of money we will have to pay. In other words, the more gas we put in, the more money we’ll pay.
A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls.
For example, the weight of a person, the number of construction workers working, the number of bananas, the amount of dog food a dog eats, the distance between two towns or the speed of a horse at a full gallop. All of these can be related with other types of magnitudes.
You use ratios and proportions in daily activities, often without realizing you are making mathematical calculations. For example, you divide a pie among four people, proportioning it equally. You talk of a car giving you 30 miles per gallon, which is a ratio. Proportion shows that two ratios (or fractions) are equal.
For example, if you’re painting a portrait of a dog and a person, the dog should be at the correct scale in relation to the person. The person’s body (and the dog’s as well) should be in a proportion to what we can recognize as a human being. Essentially, scale and proportion help the viewer make sense of the artwork.
A proportion is two ratios that are set equal to one another. An example of a proportion would be: 1 dollar10 pesos=10 dollars100 pesos As you can see, they are equivalent. The units are the same, and then we notice the fractions are equivalent. The fractions are equivalent because 10100 can be reduced to 110.
