Ratios, Rates, and ProportionsRATIOS AND PROPORTIONS INSTRUCTION SHEET Ratios A ratio is a comparison of two quantities that have thesame units. You can express a ratio in any one of the following ways: 1818:518 to 5 5 Example #1:If one store has 360 items and another store has 100 of...
Ratios, rates, and proportions all relate to each other. For example, the distance equation is D = RT, which means that distance is the product of the rate (speed) and the time traveled. If someone is traveling at a rate of 30 mph, then the ratio of the distance traveled to the tra...
A common example of proportional relationships is that between time and distance when travelling at a constant speed. Let us plot a graph that shows the relationship between distance and time for a vehicle travelling at a constant speed of 30 miles per hour. Below we have some values defining ...
” Ratios should be expressed in simplest form, where the numbers in the numerator and denominator have no common factors. A good example is: ratio of 1 to 2 = 1:2 = 1/2. A bad example is: ratios of 6 to 3 = 6:3 = 6/3. 6/3 is not in its simplest form; 2/1 would be...

Scaling involves recreating a model of the object and sharing its proportions, but where the size differs. One may scale up (enlarge) or scale down (reduce). For example, the scale of 1:4 represents a fourth. Thus any measurement we see in the model would be 1/4 ...
Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.”“For every vote candidate A received, candida...
Solving Proportions 1(8) = 2x 4(15) = 12z 8 = 2x 60 = 12z 5 = z 4 = x A little trickier 3(8) = 6(x – 3) 24 = 6x – 18 42 = 6x 7 = x X’s on both sides? 3(x + 8) = 6x 3x + 24 = 6x 24 = 3x 8 = x ...

There’s also something called a “WON” method for proportions. To do this, set up a table withWONat the top. “W” stands forWords, “O” stands forOriginalorOld, and “N” stands forNew(in this example, for Alicia). Put the words and numbers in the table, and then cross multi...
