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.

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.
