Option D
Answer:
The product of [tex]-22.2 \times -6.1[/tex] is 135.42
Solution:
When we multiply two negative numbers, the final product is a positive number.
Here we have to multiply two negative number i.e. [tex]-22.2 \times -6.1[/tex]
6.1 can also be written as (6+0.1)
Therefore we can also write it as [tex]-22.2 \times -(6 + 0.1)[/tex]
First we multiply 22.2 with 6. After the multiplication we get
[tex]-22.2 \times -6 = 133.2[/tex]
Then we multiply 22.2 with 0.1. After the multiplication we get,
[tex]-22.2 \times -0.1 = 2.22[/tex]
Now adding 133.2 and 2.22 we get (133.2+2.22) = 135.42.
Thus the product of [tex]-22.2 \times -6.1[/tex] is 135.42
