How to Solve Proportions
A proportion is an equation that states two ratios are equal. The general form is:
a/b = c/d
To solve for an unknown variable, you can use cross-multiplication:
a × d = b × c
Step-by-Step Solution
- Identify the known values in the proportion.
- Cross-multiply to create an equation with one variable.
- Solve the equation for the unknown variable.
- Verify your solution by plugging it back into the original proportion.
Tip: Always check your work to ensure the solution satisfies the original proportion.
