In this math problem we are going to test your mathematical skills in percent related operations. You also need to know how to count money and convert word problem into the mathematical equations.

To solve this challenge you have to understand what scale is and how it is related with fractional numbers. Despite pretty intricate problem’s conditions, to solve the task given you need to use arithmetical proportion. Also, make sure you know how to map word problem into the mathematical formulas and operations and back.

In this math problem we will check if you know how money is connected with basic mathematical operations and how they can interact in real life situation. You are given a certain product offered for a certain price. Your task is to name the total value of multiple products.

To solve this mathematical problem you need to know what are the basic rules of scaling and how they apply to geometrical shapes. First of all you need to identify what figure is described in task’s conditions and with the help of scale rules find the right answer.

In this challenge student’s understanding of ratio usage will be tested. One is given two different numbers. Student’s task is to find out what is the ratio number of one number to the other. Also, make sure you know what ratio or fraction "cancellation" is and how it is related with the simplest form.

This problem will test how well you can convert word problem into mathematical equations. Also, you can solve this problem in different ways using, for example, percents, fractional numbers or arithmetical proportions. But no matter what you choose, you need to remember that the problem has only one right answer.

You can solve this math problem in different ways. One of them will test if you know how to use arithmetical proportion and fractional numbers and in the other one you will need to form a couple of simple equations. But if you really want to check you math skill, we would recommend to solve this task using both variants.

This problem will test your mathematical skills in arithmetical proportions. Make sure you know how to convert a word problem in to equation that uses proportions. You will need to use multiplication and division to get to the right answer.

In this mathematical problem we will check if you know what scale is and how to use proportions. First of all, you need to understand how it is represented and what each number means (numerator, denominator). Secondly, required math operations should be made in a certain order to get the right answer.

In this challenge we are going to test your division skills. This task can be solved with the help of forming simple equation. But remember that in your answer you can get a natural number as well as a number with a remainder. If it is not natural, make sure you round it and write it down the proper way.
