Question

The integer whose product with ̶ 1 is ̶ 40 is
(a) 20
(b) ̶ 20
(c) ̶ 40
(d) 40

Answer 1

To determine the integer whose product with (-1) is (-40)

= (-1) * x = (-40)

x = -40/-1

x = 40

Therefore, The integer product with -1 is -40 is 40.

Answer 2

Given:

a number = - 40

To Find:

integer whose product with -1 gives -40

Solution:

Let "x" be the desired integer

now,

According to Question

⇒ - 1 * x = - 40

⇒ x = -40 / -1     {since ' - ' × ' - ' = +}

⇒ x = 40

So, The integer whose product with - 1 is - 40 is 40 (Option D).
