Answer 2

To solve these proportion problems, you can use the property of equivalent ratios. In each case, you want to find the value of "x" that makes the two ratios equal. Here's how you can solve each of the equations:

3. x: 18 = 2:3

Cross-multiply:

3x = 2 * 18

3x = 36

Now, divide both sides by 3 to solve for x:

x = 36 / 3

x = 12

So, x = 12 in this case.

4. 6:x = 3:7

Cross-multiply:

3x = 6 * 7

3x = 42

Now, divide both sides by 3 to solve for x:

x = 42 / 3

x = 14

So, x = 14 in this case.

5. 5:9 = 15:x

Cross-multiply:

5x = 15 * 9

5x = 135

Now, divide both sides by 5 to solve for x:

x = 135 / 5

x = 27

So, x = 27 in this case.

6. 12:7 = 60:x

Cross-multiply:

12x = 60 * 7

12x = 420

Now, divide both sides by 12 to solve for x:

x = 420 / 12

x = 35

So, x = 35 in this case.

Here are the values of x for each equation:

3. x = 12
4. x = 14
5. x = 27
6. x = 35
