Explanation:

Required

Explain how 3 * 65 could be used for (0.03) * (0.65)

0.03 is to 2 decimal places and 0.65 is also to 2 decimal places

In total, we have:
`2 + 2 = 4`

So, to get (0.03) * (0.65) from 3 * 65.

Simply calculate the product: 3 * 65

Then divide by 10 to the power of the sum of the decimal places i.e. 4

This is shown below

(0.03) * (0.65)

Express as fraction

`(0.03) * (0.65) = (3)/(100) * (65)/(100)`

`(0.03) * (0.65) = (3*65)/(100*100)`

`(0.03) * (0.65) = (3*65)/(10^2*10^2)`

`(0.03) * (0.65) = (3*65)/(10^4)`
