Detailed Solution

The value of 0.045×2.4 = 0.108.
Given, 0.045×2.4.
The decimal a.b can be written as ab10 since there is only one digit after the point. We replace the point with 10 powers in the denominator such that it has zeroes equal to the number of digits after the decimal point.
0.045×2.4  = 451000×2410
        = 45×2410000
        = 108010000
        = 0.108
Hence, 0.045×2.4 = 0.108.
