CLASS 4 Subtraction (Ex-4.1 Q4 to Q9)

GOOD  MORNING  STUDENTS! 😊😊


Today, by the end of the class you will be able to:

comprehend a word problem.
use the concept of subtraction to solve the word problem

Let's continue with Ex-4.1 (page no.45 & 46)

Q4: Find the difference between the greatest 5-digit number and the smallest 6-digit number.

Solution: (Difference between means to subtract)

Greatest 5-digit number = 99,999
Smallest 6-digit number = 1,00,000
Difference = 1,00,000 - 99,999 = 1

          100000
        -   99999
           000001

Q5: What should we add to 61859 to get 432162?

Solution: Here, though the word add is used but we are subtracting because if the question asks about- What should we add to or What should we subtract from....then we always SUBTRACT.

                    432162
                 -    61859
                    370303 → Answer.


Q6: Subtract: Seven lakh eighty five thousand nine hundred sixty seven from nine lakh seventy six thousand nine hundred eighty six. 

 Solution: Let's write the numerals for the number names first.

 Subtract 7,85,967 from 9,76,986. 
[Hint: If there is a word 'from' in subtraction, then the bigger number is after from and smaller number is before.]

Thus,    976986
           -  785967
              191019 → Answer

Q9: If the difference is 72946 and the subtrahend is 28476, Find the minuend.

Solution: As, we know that
                  DIFFERENCE + SUBTRAHEND = MINUEND.

                 DIFFERENCE   =     72946
                 SUBTRAHEND =  + 28476
    Thus,    MINUEND         =   101422

HOMEWORK
Do Q7 & Q8 of Ex-4.1 (page no.46)

Q7: [Hint: Write numerals of the given number names.
           and subtract]
Q8: [Hint: Difference = Minuend - Subtrahend].

That's all for today
