Samacheer Kalvi Class 5 Maths Solutions Term 1 Chapter 2 Numbers Exercise 2.6

Subtract

Question 1. Subtract 59,475 from 78,347.
Answer:78,347
\( \underline{(-) 59,475} \)
18,872
When you take 59,475 away from 78,347, the number that is left is 18,872. This is a basic subtraction problem, which helps in understanding how to find the difference between two numbers.
In simple words: Taking 59,475 from 78,347 leaves you with 18,872.

🎯 Exam Tip: Always align numbers by their place values (ones, tens, hundreds, etc.) when doing subtraction to avoid errors, especially when borrowing from higher places.

Question 2. Subtract 3,748 from 67,056.
Answer:67,056
\( \underline{(-) 3,748} \)
63,308
The difference when 3,748 is subtracted from 67,056 is 63,308. This process shows how to find the remaining quantity after removing a smaller part from a larger one.
In simple words: When you subtract 3,748 from 67,056, you get 63,308.

🎯 Exam Tip: Remember to borrow from the next place value when a digit in the top number is smaller than the digit below it. This is a common step in multi-digit subtraction.

Question 3. Subtract 47,978 from 1,58,376.
Answer:1,58,376
\( \underline{(-) 47,978} \)
1,10,398
Subtracting 47,978 from 1,58,376 results in 1,10,398. This subtraction shows how to find the exact amount that is left after a certain value is taken away.
In simple words: The result of 1,58,376 minus 47,978 is 1,10,398.

🎯 Exam Tip: Pay close attention to the borrowing process across multiple place values, especially when zeros are involved, to ensure accuracy in larger number subtractions.

Question 4. Subtract 4,538 from 89,700.
Answer:89,700
\( \underline{(-) 4,538} \)
85,162
The calculation of 89,700 minus 4,538 gives an answer of 85,162. This demonstrates how to correctly subtract a four-digit number from a five-digit number, often involving borrowing.
In simple words: When 4,538 is taken away from 89,700, 85,162 remains.

🎯 Exam Tip: When subtracting numbers with differing numbers of digits, ensure they are correctly aligned by their rightmost digit (ones place) before performing the calculation.

Question b. Rahul has 3,289 stamps. Ravi has 4,021 stamps. How many stamps does Ravi have more than Rahul?
Answer:Ravi has: 4021 stamps
Rahul has: \( \underline{(-) 3289} \) stamps
Difference: 732 stamps
So, Ravi has 732 stamps more than Rahul. This problem uses subtraction to compare two quantities and find the difference between them, telling us how much more one person has.
In simple words: Ravi has 732 more stamps than Rahul.

🎯 Exam Tip: For "how many more" or "how many less" questions, always use subtraction to find the difference between the two quantities mentioned.

Question c. Create the story problem by using the pictures given below:
(i) Using the picture of the computer (Rs. 15672) and printer (Rs. 6276), create a story problem.
Answer: The story problem could be: The cost of a computer is Rs. 15672 and the cost of a printer is Rs. 6276. Find the total cost. This type of question helps you to practice forming real-world scenarios that match given numbers and an operation (like addition here).
In simple words: We can make a problem asking for the total cost of a computer (Rs. 15672) and a printer (Rs. 6276).

🎯 Exam Tip: When creating a story problem, make sure the question clearly asks for an operation (like "find the total" for addition) that can be solved using the given numbers.

Question c. (ii) Using the picture showing two paths and distances (7845m and 4782m), create a story problem.
Answer: The story problem could be: A car needs to find two ways to reach a village. The first path is 7845 meters long and the second path is 4782 meters long. Which way is the shortest distance, and how many meters lesser is it than the longest distance? This helps students to understand how to apply mathematical operations like subtraction to real-life situations involving comparison.
In simple words: A problem could be about comparing two paths to a village (7845m and 4782m) to find the shorter path and the difference in length.

🎯 Exam Tip: For comparison problems, ensure your story problem clearly identifies the two items being compared and asks for their difference or which is greater/smaller.
