Question

Evaluate the following, using suitable property.
(i) -45 × 98

Answer 1

here we will use distributive property
-45x(100-2)=(-45x100)-(-45x2)
=-4500-(-90)
=-4500+90
=4410ans

plz mark me as brainliest

Answer 2

The property that must be used here is distributive property of multiplication over subtraction.

Explanation:

-45 × 98

98 = 100 - 2

-45 × (100-2)

(-45 × 100) - (-45 × 2)

a × (b-c) = (a×b) - (a×c)

-4500 - (-90)

-4500 + 90

-4410.

Distributive property of multiplication over subtraction:

Distribution means to distribute something or to divide something. It helps to simplify a multiplication of two numbers. It states that multiplying two numbers gives the same result as if we split one of the number in two addends and then multiply each addend by the second number.

This property helps in making the complex multiplications easier by breaking the numbers in two simple or shorter numbers.

Operand: The number which is distributed into two parts is called an operand.

Addends : The numbers which are added or subtracted in the bracketd are called addends.
