3. Emma said that when you multiply three negative decimals , the product will be positive . Use these numbers to answer the que
mina [271]

Using multiplication signal rules, it is found that:

A: Emma's statement is always false.

B: The result is always negative.

C: Emma's statement is always true.

The rule used for this exercise is as follows:

  • When two numbers of different signals are multiplied, the result is negative.
  • When two numbers have the same signal, the result is positive.

Part A:

  • Three numbers are multiplied, all negative.
  • The multiplication of the first two result in a positive number.
  • Then, this positive number is multiplied by a negative number, and the result will be negative, which mean that Emma's statement is always false.

Two examples are:

-2.5(-3.8)(-2) = 9.5(-2) = -19

-2.5(-2)(-0.7) = 5(-0.7) = -3.5

Part B:

The rule is that the result is always negative.

Part C:

  • The multiplication of the first two negative numbers result in a positive number.
  • Then, this positive number is multiplied by another positive number, and the result will be positive, which mean that Emma's statement is always true.

Two examples are:

-2.5(-3.8)(2) = 9.5(2) = 19

-2.5(-2)(0.7) = 5(0.7) = 3.5
