When it comes to solving proportions, using the correct rounding to the nearest hundredth is key. Rounding to the nearest hundredth means that the number following the decimal point will be rounded to the closest two digits. Although this may sound simple, it can be difficult to do correctly. This article will explain how to solve proportions and round to the nearest hundredth.
What is a Proportion?
A proportion is an equation that states two ratios are equal. It is written in the form a/b = c/d. To solve a proportion, you must determine the missing information by using cross-multiplication. This is the process of multiplying the numerator and denominator of one ratio with the denominator and numerator of the other ratio. This will result in an equation that can be solved for the missing variable.
Steps to Solve a Proportion
The first step in solving a proportion is to determine what information is missing. Then, you can use cross-multiplication to create an equation that can be solved. After solving the equation, it’s important to check your answer by substituting the solution into the original proportion. If the two sides are equal, then you know your answer is correct. Once you’ve verified your answer, you can round to the nearest hundredth.
Rounding to the Nearest Hundredth
Rounding to the nearest hundredth means that you will round the number following the decimal point to the closest two digits. This can be done by looking at the third number after the decimal point. If it is 5 or higher, then round up to the next two digits. If it is 4 or lower, then round down to the previous two digits. For example, if the number is 4.853, then you would round to 4.85. On the other hand, if the number is 4.857 then you would round to 4.86.
Solving proportions and rounding to the nearest hundredth can be tricky, but with the right steps, it can be done correctly. First, determine what information is missing in the proportion. Then, use cross-multiplication to create an equation that can be solved. Finally, round to the nearest hundredth by looking at the third number after the decimal point. With practice, you will be able to solve proportions and round to the nearest hundredth with ease.
