# TASC Math Exam: Comparing Fractions, Decimals, and Percentages

Numbers come in all shapes, sizes, and forms, such as fractions, decimals, and percentages. When a TASC Math question asks you to compare numbers or put a set of numbers in a certain order, it’s easiest to do when they’re all in the same form.

## Practice questions

1. Which of the following is listed in ascending order? 2. Which of the following is in descending order? ## Answers and explanations

1. The correct answer is Choice (A).

Comparing numbers in different forms can be difficult, so you want to rewrite them all into the same form (usually decimals is the easiest). .6 is already a decimal, and 350% = 3.5. Now that they’re all in decimal form, you need to remember what ascending means: smallest to largest. This means the order should be Substituting back in the original values, you get: which is Choice (A).

2. The correct answer is Choice (D).

First rewrite each of the numbers into the same form (decimal form is probably the easiest). Now you can order them in descending order, which means from largest to smallest: 2.64, .7, .05, .03 and then substitute your original numbers back in: thus Choice (D) is correct.
