yKpoI14uk [10]

Answer:

Result = 0.0045

Step-by-step explanation:

Given

0.09 * 0.05

Required

Determine the result

Following Charlie's steps:

So, the product is as follows:

9 --------- 2 decimal place

5 --------- 2 decimal place

------------------------------------------

45 --------- 4 decimal place

Shifting the decimals in 45 to 4 decimal places will give us: 0.0045

<em>Hence, the final answer is 0.0045</em>
