Question

Complete the following statements by filling in the blanks.

(1) 21 ÷ 7 = ........ ∵ 21 = 7 × 3
(2) 45 ÷ 15 = ....... ∵ 45 = ......... × ........
(3) We continue to carry out division until we get remainder zero or a whole number less than the ........ .
(4) Dividend = divisor × (......) + (......), 0 ≤ remainder < divisor
(5) When we divide 43 by 5, the quotient is ....... and the remainder is ........ .
Here, dividend ........., divisor = ........
∴ 43 = 5 × ...... + .......
(6) 2y × ......... = 10y²
(7) 5x × ......... = 15x⁴
(8) m² × ........ = 9m⁴
(9) 3m × ........... = 9m⁴

Answer 1

(1) 21 ÷ 7 = 3 ∵ 21 = 7 × 3
(2) 45 ÷ 15 = 3 ∵ 45 = 15 × 3
(3) We continue to carry out division until we get remainder zero or a whole number less than the divisor.
(4) Dividend = divisor ×(quotient) + remainder, 0 ≤ remainder < divisor
(5) When we divide 43 by 5, the quotient is 8 and the remainder is 3 .
Here, dividend = 43, divisor = 5
∴ 43 = 5 × 8 + 3
(6) 2y × 5y = 10y²
(7) 5x × 3x³ = 15x⁴
(8) m² × 9m² = 9m⁴
(9) 3m × 3m³ = 9m⁴
