Question

Simplify the expression:

$(0.08\times{1.1}\times{0.05}\times{0.9})$

• A. 0.00396
• B. 0.000396
• C. 0.0000396
• D. 0.00000396

Answer 1

Answer:

A. 0.00396

Given:

$(0.08\times{1.1}\times{0.05}\times{0.9})$

Calculation:

$0.08\times{1.1}\times{0.05}\times{0.9}=8\times{0.01}\times{11}\times{0.1}\times{5}\times{0.01}\times{9}\times{0.1}$

 

$=8\times{11}\times{5}\times{9}\times{10^{-6}}$

$=3960\times{10^{-6}}$

=0.003960=0.00396

∴ The value of the expression is 0.00396.
