Worked example: Solving proportions (video)
The video is a bit confusing, and I'm struggling to transfer this to solving the questions for "Solving Proportions". For example in the question: 4/z = 12/5 I understand that you begin by multiplying by z. z * 4/z = 12/5*z--> 4 = 12/5*z After this, the solution set asks you to multiply both sides by 5/12, the opposite fraction of the right side.
6.6: Solve Proportions and their Applications
Solve Proportions. To solve a proportion containing a variable, we remember that the proportion is an equation. All of the techniques we have used so far to solve equations still apply. In the next example, we will solve a proportion by multiplying by the Least Common Denominator (LCD) using the Multiplication Property of Equality.
1.4: Proportions
In solving this problem before, we set up two ratios \[3752 \colon x \quad \text{and} \quad 13 \colon 1 \] Why did we do this? Well, it turns out that all proportion problems can be solved using a method from algebra known as cross multiplication.While this text mostly stays away from algebra, this procedure is essential.

8 Ways to Solve Proportions
Find the product of these two numbers: 3. Divide by the last number in the proportion. Take the answer to your multiplication problem and divide it by the number you haven't used yet. (This is the green number in the example.) The result is the value of , the missing number in your proportion.

Proportions
Proportion says that two ratios (or fractions) are equal. Example: We see that 1-out-of-3 is equal to 2-out-of-6. The ratios are the same, so they are in proportion. Example: Rope. A rope's length and weight are in proportion. When 20m of rope weighs 1kg , then: So: 20 1 = 40 2.
8.7 Solve Proportion and Similar Figure Applications
Solve geometry applications. Step 1. Read the problem and make all the words and ideas are understood. Draw the figure and label it with the given information. Step 2. Identify what we are looking for.; Step 3. Name what we are looking for by choosing a variable to represent it.; Step 4. Translate into an equation by writing the appropriate formula or model for the situation.
Proportion Word Problems
Proportion word problems. There are lots of situations that can create proportion word problems. We will illustrate these situations with some examples. Problem # 1. Mix 3 liters of water with 4 lemons to make lemonade. How many liters of water are mixed with 8 lemons. Set up the ratios, but make sure that the two ratios are written in the same ...
Proportion
The original price of a shirt is $30. There is a 15% sale on the shirt. Use proportions to find the price of the shirt after the 15% discount. We set this problem up first by converting the 15% to a ratio: Then we set this equal to the ratio of the price: So, 15% of $30 is $4.50, and the final price of the shirt is: $30 - $4.50 = $25.50

6.5 Solve Proportions and their Applications
Try It 6.84. Solve the proportion: y 96 = 13 12. When the variable is in a denominator, we'll use the fact that the cross products of a proportion are equal to solve the proportions. We can find the cross products of the proportion and then set them equal. Then we solve the resulting equation using our familiar techniques.

Try It 8.7.8 8.7. 8. 2x + 15 9 = 7x + 3 15 2 x + 15 9 = 7 x + 3 15. Answer. To solve applications with proportions, we will follow our usual strategy for solving applications. But when we set up the proportion, we must make sure to have the units correct—the units in the numerators must match and the units in the denominators must match.

Ratios and proportions
It compares the amount of one ingredient to the sum of all ingredients. part: whole = part: sum of all parts. To write a ratio: Determine whether the ratio is part to part or part to whole. Calculate the parts and the whole if needed. Plug values into the ratio. Simplify the ratio if needed.
5.2: Applications of Proportionality
Also notice how we've labeled our units, and have made sure that the corresponding quantities are together. If you do this every time -- label your units, and make sure corresponding quantities stay together -- you can solve any direct proportion problem. Now for the process that will actually help us solve for \(x\).

Writing proportions example (video)
So you could say that the ratio of 9 markers to the cost of 9 markers, so the ratio of the number of markers, so 9, to the cost of the 9 markers, to 11.50, this should be equal to the ratio of our new number of markers, 7, to whatever the cost of the 7 markers are, to x. Let me do x in green. So this is a completely valid proportion here.

A proportion is basically a relationship between two numbers that is always constant. If you were to graph a proportion, it would be a straight line that passes through the origin (0,0). In the F and C question you had, the relationship would be F=1.8C+32, or f (C)=1.8C+32. It is not proportional because it doesn't pass through the origin.
7.3: Applications of Proportions
The five-step method for solving proportion problems: By careful reading, determine what the unknown quantity is and represent it with some letter. There will be only one unknown in a problem. Identify the three specified numbers. Determine which comparisons are to be made and set up the proportion. Solve the proportion (using the methods of ...
