Missing Proportions worksheet for practicing proportion problems.

It looks like you've uploaded an image of a worksheet titled "Missing Proportions", which contains a series of proportion problems where one number is missing and needs to be found.

Since I can't view images directly, I’ll need you to provide the actual problems from the worksheet (either by typing them out or describing them). However, based on the typical format of such worksheets, here’s how you would solve a missing proportion problem:

🔍 What is a Proportion?

A proportion is an equation that states two ratios are equal. It looks like this:

$$
\frac{a}{b} = \frac{c}{d}
$$

If one of the values is missing, you can solve for it using cross-multiplication:

$$
a \cdot d = b \cdot c
$$

Then solve for the unknown.

✔ Example Problem:

Let’s say one of the problems is:

$$
\frac{2}{3} = \frac{x}{6}
$$

Step 1: Cross-multiply:

$$
2 \cdot 6 = 3 \cdot x \Rightarrow 12 = 3x
$$

Step 2: Solve for $ x $:

$$
x = \frac{12}{3} = 4
$$

So, the missing number is 4.

🧩 How to Solve Each Problem on the Worksheet

You’ll follow the same process for each problem. Here's a general method:

1. Write the proportion as a fraction equation.
2. Cross-multiply.
3. Solve for the missing variable.

Please provide the actual problems from the worksheet (e.g., list the equations), and I’ll help you solve each one step-by-step! For example:

- "2 : 3 = 4 : ?"
- "? : 5 = 8 : 10"

Just type them out, and I’ll walk you through solving them all.
