Mathematical Reasoning
GED Math Practice Test 7
Forty new multiple-choice questions, none repeated from earlier tests. Twenty-two are algebra, with extra weight on turning words into equations, systems, inequalities, and slope, and the rest cover number operations, geometry, and data analysis. Use this set to practice getting unstuck: how to use the answer choices when you cannot see where to start.
Question 1 of 40
0 answered
A bakery sells muffins for $2.50 each. A customer pays with a $20 bill and gets $7.50 in change. Which equation can be used to find the number of muffins m the customer bought?
Use the answer choices as a tool
Every question on this test gives you four options, and one of them is right. When an equation will not come together, try working backward: put each choice into the question and see which one fits. For a question like “how many adults were in the group,” start with a middle value. If it gives a total that is too high, you can skip every larger choice too.
You can also cross out choices that cannot be right before doing any math. A width cannot be longer than the length it was taken from, a probability cannot be greater than 1, and a sale price cannot be more than the original. Removing even one choice turns a blind guess into a better one, and a wrong answer costs nothing more than a blank one.
Mix your review after this test
After you score this test, do not spend the next week on only one topic. Short, mixed sessions work better: ten questions from your weakest topic, five from a topic you know well, and a few you missed on an earlier test. Mixing forces you to decide which method a problem needs, which is exactly what the real test asks you to do.
Space the sessions out. Twenty minutes on four different days builds more lasting skill than eighty minutes in one night. Before each session, try one question from memory that you missed last time. If you can solve it cleanly, move it off your list.
Frequently asked questions
- Is working backward from the answers a real strategy or a trick?
- It is a real strategy. On a multiple-choice test, checking a choice against the question is a valid way to solve it, and it also shows you how the problem fits together. Use it when setting up the equation is taking too long.
- What should I do in the week after taking Practice Test 7?
- Plan three or four short sessions that mix your weakest topic with a little of everything else. Retry the questions you missed without the explanation, and save a test you have not taken for the end of the week.
