Question

Find the product:

$0.05\times 0.09\times 5$

• A. $0.025$
• B. $0.225$
• C. $0.005$
• D. $0.0225$

Answer 1

Answer: (D)

$0.0225$

Multiply the numbers without decimal point

i.e. $5\times 9\times 5=225$

$0.05$ have decimal point after $2$ digits

$0.09$ have decimal point after $2$ digits

So, the product will have decimal point after $2+2=4$ digits

Thus, the product of $0.05\times 0.09\times 5=0.0225$
