You'll encounter questions that require converting percentages to decimals or fractions, calculating percentage increases or decreases, and finding the percentage of a given number.

For ratios, you'll practice simplifying, comparing, and solving word problems involving proportions and rates.

Percentage Calculations

In the world of CBEST math, percentage calculations play a crucial role. You'll need to master converting between percentages, decimals, and fractions to excel in this area. Remember that a percentage is simply a fraction with a denominator of 100, so 25% is equivalent to 25/100 or 0.25.

To calculate a percentage of a number, multiply the number by the percentage expressed as a decimal. For instance, to find 15% of 80, multiply 80 by 0.15, which equals 12.

When increasing or decreasing a value by a percentage, first calculate the change, then add or subtract it from the original amount. For a 20% increase on $50, you'd multiply 50 by 0.20 to get 10, then add 10 to 50 for a total of $60.

Practice solving word problems involving percentages, such as discounts, tax calculations, and interest rates. You might encounter questions about percent change, where you'll need to calculate the difference between two values as a percentage of the original value.

Don't forget to review percentage comparisons and how to express one quantity as a percentage of another.

Ratio Problem-Solving Techniques

Ratio problem-solving techniques are essential for mastering CBEST math questions involving percentages and ratios. You'll need to understand how to set up and solve ratio equations, as well as how to interpret ratio-based word problems.

Start by recognizing that ratios compare two quantities and can be expressed in various forms, such as 3:4, 3/4, or "3 to 4."

To solve ratio problems, you'll often use cross-multiplication or the concept of equivalent ratios. For example, if you're told that the ratio of boys to girls in a class is 2:3 and there are 15 girls, you can set up the equation 2/3 = x/15 to find the number of boys. Cross-multiply to solve for x.

When dealing with complex ratios, break them down into simpler parts. If you're given a ratio of three quantities, like 2:3:4, consider the total parts (2+3+4=9) to calculate individual proportions.

Practice simplifying ratios to their lowest terms and converting between ratios, fractions, and percentages. Remember, a ratio of 1:4 is equivalent to 1/5 or 20%.

Mastering these techniques will help you tackle a wide range of CBEST ratio questions confidently.
