Answers:

2- B
The question is this: 530.40 is what percent of 624?
Use percent formula:
\(part =\frac{percent}{100}× whole\)
\(530.40 =\frac{percent}{100}× 624\)
\(530.40 =\frac{percent× 624}{100}\)
\(⇒53040 = percent ×624 \)
\(percent = \frac{53040}{624}= 85\)
530.40 is \(85 \%\) of 624. Therefore, the discount is: \(100\% – 85\% = 15\%\)

3- B
If the score of Mia was 60, therefore the score of Ava is 30. Since the score of Emma was half as that of Ava, therefore, the score of Emma is 15.

4- D
If 17 balls are removed from the bag at random, there will be one ball in the bag.
The probability of choosing a brown ball is 1 out of 18. Therefore, the probability of not choosing a brown ball is 17 out of 18 and the probability of having not a brown ball after removing 17 balls is the same.

5- B
Let \(x\) be the smallest number. Then, these are the numbers:
\(x, x+1, x+2, x+3, x+4\)
\(average = \frac{sum \space of \space terms}{number \space of \space terms}\)
\(38 = \frac{x+(x+1)+(x+2)+(x+3)+(x+4)}{5}\)
\(38=\frac{5x+10}{5}\)
\(⇒ 190 = 5x+10 ⇒ 180 = 5x ⇒ x=36\)

6- C
The area of the floor is: \(6 \)cm \(× 24\) cm \(= 144\) cm
The number is tiles needed \(= 144 ÷ 8 = 18\)

7- C
The weight of 12.2 meters of this rope is: \(12.2 × 600 g = 7320 g\)
\(1 kg = 1000 g\), therefore, \(7320 g ÷ 1000 = 7.32 kg\)

8- C
\(4\%\) of the volume of the solution is alcohol. Let \(x\) be the volume of the solution.
Then: \(4\%\) of \(x = 24\) ml \(⇒ 0.04 x = 24 ⇒ x = 24 ÷ 0.04 = 600\)

9- B
\(average =\frac{sum \space of \space terms}{number \space of \space terms}\)
The sum of the weight of all girls is: \(18 × 60 = 1080\) kg
The sum of the weight of all boys is: \(32 × 62 = 1984\) kg
The sum of the weight of all students is: \(1080 + 1984 = 3064\) kg
\(average =\frac{3064}{50}= 61.28\)

10- C
Let \(x\) be the original price.
If the price of a laptop is decreased by \(10\%\) to $360, then: \(90 \%\) of \(x=360⇒ 0.90x=360 ⇒ x=360÷0.90=400\)

How to use HiSET Math Practice Test Questions as real practice

HiSET Math Practice Test Questions works best when it is used as a short, focused study session rather than a quick click-through activity. The goal is not simply to finish the questions. The goal is to notice which skills feel automatic, which skills still need review, and which mistakes happen when you rush.

Start with a clean piece of scratch paper. For each item, answer the questions under realistic conditions, then review every missed problem before retaking a similar set. If you get something wrong, do not immediately move on. Write the correct step, circle the part that caused the mistake, and try one similar item before continuing. That small correction habit is what turns an online practice test into lasting math improvement.

A three-round study routine

This routine is simple, but it solves a common problem: students often practice only until an answer looks familiar. Real readiness means you can solve a fresh problem without hints, explain the first step, and check whether the final answer is reasonable.

What to write down while you practice

Keep a tiny mistake log next to the activity. You only need three columns: the topic, the mistake, and the correction. For example, a student might write “fractions,” “forgot common denominator,” and “rewrite both fractions before adding.” A log like that is more useful than a long list of scores because it tells you exactly what to review next.

• If the mistake is a fact or formula, review it before the next round.
• If the mistake is a setup error, copy one worked example and label each step.
• If the mistake is from rushing, slow down and require written work for the next five items.
• If the same mistake appears twice, stop and review that topic before continuing.

When you are ready to move on

You are ready for the next topic when you can get several items correct in a row and explain why the method works. A score by itself is helpful, but it is not the whole story. You should also be able to describe the rule, formula, or pattern that the activity is testing.

For test preparation, come back to HiSET Math Practice Test Questions after a day or two and try a fresh round. If the skill still feels easy after a short break, it is much more likely to stay with you during a quiz, unit test, or standardized test. If it feels shaky, that is useful information too: it tells you exactly where to spend your next study session.

Study tips for parents and teachers

When using this page with a student, ask for the reasoning before the answer. Questions such as “What is the first step?”, “Why did you choose that operation?”, and “How can you check it?” help students build mathematical language. That matters because many test questions measure more than calculation; they also measure whether the student can read the problem, choose a method, and explain a result.

Short sessions are usually best. Ten to fifteen minutes of careful practice can be more productive than a long session full of guessing. End by naming one skill that improved and one skill to review next time. That keeps practice positive, specific, and easy to continue.
