Multiplication is the second basic arithmetic operation. It combines two terms into a single term.
Division is opposite to multiplication. Any number when divide by 0 is undefined.
Dividend = Divisor x Quotient + Remainder
Multiplication and division are inverse operations. To solve the equations first observe the operation which is applied and then an inverse operation is to be applied to undo that.
Example: 5x = 15
Multiplication is used here. So apply the inverse of that (division).
5x5 = 155
x = 3
1) 6 ÷57=
(a) 307                     (b) 425                      (c) 542                      (d) 730
Answer: b
2) 60 =
(a) 0                         (b) 6                     (c) 1                     (d) Not possible
Answer: d
3) Multiply 3p and 4p² + 5p + 8
Answer: 3p ( 4p² + 5p + 8)
= 12p³ + 15p² + 24p
4) Divide 16p² - a² with 4p + a
(a) 4p + a                   (b) 4p – a                 (c) 16p + a             (d) 16p – a
Answer: b
5) Divide 8a³ - 27 with 4a² + 6a + 9
(a) 2a + 3                   (b) 4a + 3                 (c) 4a – 3             (d) 2a – 3
Answer: d
