Option A
<u>Answer:
</u>
The product of -4 and 8.1 is -32.4
<u>Solution:
</u>
When we multiply a negative number with a positive number we get the resultant product as a negative number.
Here we have to multiply - 4 which is a negative number and 8.1 which is a positive number.
To simplify the multiplication calculation we can write 8.1 as 8+0.1 and then multiply 4 with both 8 and 0.1
-4
8.1 = -4
(8+0.1)
⇒ -4
8.1 = -4
8 – 4
0.1 [Multiplying 4 with 8 and 0.1]
⇒ -4
8.1= -32 - 0.4
⇒ -4
8.1= - 32.4
Thus the product of -4 and 8.1 is -32.4
