Q4: The quotient of any number divided by itself is __________.

Ans: “1”

Q5: If you divide zero by a number, the result is __________.

Ans: “0”

True or False

Q1: Division by zero is defined. 

Ans: “False”
Division by zero is not defined because no number can be divided by zero in mathematics. It leads to an undefined result. Hence, the statement is False.

Q2: The remainder can be equal to the divisor. 

Ans: “False”
The remainder in a division operation is always less than the divisor. For example, in 10÷3, the remainder is 1, which is less than 3. Hence, the statement is False.

Q3: Division of a number by 1 always results in the number itself. 

Ans: “True”

Q4: The quotient of any number divided by itself is always greater than one. 

Ans: “False”
When a number is divided by itself (except zero), the quotient is always 1. For instance, 5÷5=1, which is not greater than one. Hence, the statement is False.

Q5: To divide by 10, you remove the last digit. __________

Ans: “True”

Answer the following questions

Q1: I want to distribute Rs 3,600 among 8 persons. How many rupees will each person get?
Ans:
Total Rs. = 3600
To be distributed among = 8 persons
3600 ÷ 8 = 450Answer the following questions450 Rs. per person

Q2: In a division, divisor = 100, quotient = 25 and remainder = 75, find the dividend.
Ans:
Divisor = 100, Quotient = 25 and Remainder = 75
Dividend = Quotient x Divisor + Remainder.
Dividend = 25 x 100 + 75 = 2575

Q3: In a division, remainder is always ______ than the divisor.
Ans: The remainder is always less than the divisor. If the remainder is greater than the divisor, it means that the division is incomplete. It can be greater than or lesser than the quotient.

Q4: 6308 ÷ 100 gives quotient = ______ and remainder = ______.
Ans: 6308 ÷ 100 gives quotient = 63 and remainder = 8.Answer the following questions
Q5: Manish has Rs 84. The cost of one pencil box is Rs 14. How many pencil boxes can Manish buy for Rs 84?
Ans:

  • Total money = RS 84
  • Cost of 1 pencil box = RS 14
  • Then cost of x pencil boxes is = 84 ÷ 14 = 6Answer the following questions
  • So, x = 6

Q4: Round off the following numbers to the nearest tens

(i) 13,528
Ans: Here’s the general rule for rounding:

  • Number >= 5: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
  • Number < 5: If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Therefore, applying these rules, we get:
13,528 = 13,530

(ii) 3,542
Ans: Here’s the general rule for rounding:

  • Number >= 5: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
  • Number < 5: If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Therefore, applying these rules, we get:
3,542 = 3,540

(iii) 174
Ans: Here’s the general rule for rounding:

  • Number >= 5: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
  • Number < 5: If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Therefore, applying these rules, we get:
174 = 170

(i) 52 x 43
Ans: Here’s the general rule for rounding:

  • Number >= 5: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
  • Number < 5: If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Therefore, applying these rules, we get:
52 x 43 = 50 x 40 = 2000

(ii) 63 x 52
Ans: Here’s the general rule for rounding:

  • Number >= 5: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
  • Number < 5: If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Therefore, applying these rules, we get:
63 x 52 = 60 x 50 = 3000

Q6: Answer the following Questions

(i) Calculate the product of the place values of the two 6s in the number 6,965.

Ans: The place value of 1st 6 in 6,965 is at thousand’s place.
=> First place value of 6 = 6000
The place value of 2nd 6 in 6,965 is at ten’s place.
=> Second place value of 6 = 6000
Product of the place values of 6 in the number 6,965 = 6000 x 60 = 360000

(ii) Find the product of the greatest 2-digit number and the smallest 4-digit number ______.
Ans: Greatest 2-digit no. = 99
Smallest 4-digit no. = 1000
Therefore, the product of the greatest 2-digit number and the smallest 4-digit number = 1000 x 99 = 99000.

(iii) A transistor costs Rs. 1,642. Find the cost of 95 such transistors. 

Ans: Cost of one Transistor = Rs 1,642
Total number of transistors = 95
Cost of 95 Transistors = 1642 x 95 = 155,990

(iv) A candle factory produced 814 candles in a day. How many candles will this factory produce in a year?

Ans: A candle factory produces candles in a day = 814
Total  number of days in a leap year = 365
Candles this factory will produce in one year = 814 x 365 = 2,97,110

(v) A farmer produced 735 quintals of rice. He sold it at the rate of Rs 1525 per quintal. How much money did he get?
Ans: A farmer produced rice = 735 quintals
Cost per quintal = Rs. 1525
Money he got = 1525 x 735 = Rs. 1,120,875

(vi) The cost of a pack of Ghee is Rs. 308 Find the cost of 97 such packs.
Ans: The cost of 1 pack of Ghee = Rs. 308
Total number of packs = 97
Therefore, Total Cost of 97 packs of Ghee = 308 x 97 = 29,876
