Have you ever come across a situation where you are attempting a math problem and need to check whether you did it right or not? When you find the solution, a good way to check if the problem is solved correctly is to check for reasonableness. While solving a problem, you should always ask yourself whether your answer is logical and appropriate or ...
What does reasonable mean in math? Well, all it means is being moderate or fair while finding a solution and not excessive than the actual number or what is reasonable within the context of the given factors or values. This is the simple meaning of reasonableness. When solving a math problem, we can check if the answer we have derived is reasonable...
In math, reasonableness can be defined as checking or verifying whether the result of the solution or the calculation of the problem is correct or not. We can do it by either estimating or plugging in your result to check it. We use convenient numbers to find an estimate and then compare this estimate to the actual answer to check for reasonablenes...
There are various situations where we use reasonableness. We use it to cross-verify our addition, multiplication, division, and even other complex mathematical problems.
Students often make mistakes while carrying out multiplication of two large numbers. This method helps gain confidence and makes sure that the answer is not outrageous. For example, let’s multiply 51 and 41. In the first step, round 51 to 50 and 41 to 40. Multiply 50 and 40. 50×40=2000. The actual product is given by 50×40=2091. Now we subtract 200...
We can solve and verify the division problems using estimation. Round the divisor and the dividend to the closer and convenient value and check whether the actual answer is reasonable or not. For example, let’s find the answer to 21001518. 1. Round up the dividend to 2000 and the divisor to 1500. 2. Here you can estimate that the solution to 200015...
Rounding numbers, making numbers compatible, and properties of operations are some strategies that are used to check the reasonableness of answers.
In this article, we learned about the concept of reasonableness. We came across some conditions like multiplication and division and how we use reasonableness in such cases. We can now look at some examples and solve some practice problems to better understand reasonableness.
1. Solve 45×5using reasonableness. Solution: On calculating 45×5, we get 225. Now, for the sake of reasonableness, if we divide 225 by 5, We get 2255=45. Hence, we verified using reasonableness. 2. Anne bought 3.8 pounds of grains. The grains cost her $1.99per pound. What was the total cost of Anne’s grains? Also, find a reasonable estimate. Soluti...
