Word problems are mathematical questions presented in words rather than just numbers. They often involve reallife situations and require you to use math to solve them. Let's take an example and see how to solve word problems?
Example Problem: Kishan has 456 saplings in August. He distributed 63 saplings. How many saplings are left with him?
Solution:
Identify Given Information:
Set Up the Equation: To find out how many saplings are left, we subtract the distributed saplings from the total saplings:
$Total\; saplingsSaplings\; left\backslash text\{Total\; saplings\}\; \; \backslash text\{Distributed\; saplings\}\; =\; \backslash text\{Saplings\; left\}$Total saplings−Distributed saplings=Saplings left $45663=?456\; \; 63\; =\; \backslash text\{?\}$?Solve the Equation: Starting from the right side, we do the subtraction:
Putting it all together: $45663=393456\; \; 63\; =\; 393$
Conclusion: Kishan has 393 saplings left with him after distributing 63 saplings.
In summary, when solving word problems, it's crucial to identify the given information, set up the equation based on what you're asked to find, solve the equation step by step, and then conclude with the answer and what it means in the context of the problem.
Estimating values is important because it helps us quickly understand and make decisions about quantities without needing exact numbers, making math and reallife situations easier to handle.
Let's take a number : 156 + 34
Steps:
Identify the Numbers:
Locate the Hundreds Place:
Round to the Nearest Hundred:
Add the Rounded Numbers:
Calculate the Estimate:
A number can be made using different combinations. let's see an example:
Example 1: Making 42 Rupees
Example 2: Making 42 Rupees (Alternative)
Explanation: When we need to make a specific amount of money, we can use different combinations of notes and coins to reach that total. Let's break down the examples:
