Description
In this second quiz on percentage, ratio, and proportion, we will go further into studying their applications in mathematical problems. They can also be applied in physics and even in real-life situations. This section of mathematics has to deal with more practical applications. If you are facing problems with this, don’t bother. This quiz will aid you in understanding it well.
A percentage can be defined as a number expressed as a fraction of 100. It is usually denoted with the sign ‘%’. Let’s take 50% as an example. 50% means 50/100 which is ½ of a hundred. Percentages are dimensionless, meaning they have no unit. On the other hand, a ratio refers to the number of times a number contains another. For example, if in a bowl we have eight apples and six bananas, the ratio of apples to bananas is eight to six. This is usually written as 8:6. This ratio is equivalent to 4:3. Ratios can also be considered as an ordered pair of numbers. Finally, two varying quantities are said to be proportional if they are multiplicatively connected to a constant. The value of this constant is known to be the constant of proportionality. For example, F and a are proportional in the equation F = ma, where m is the constant of proportionality.
We have come to the end of this brief recap. Now it’s time to put to practice what you have learned so far by answering this mathematics quiz. Good luck.
