Preschool newbie

Hello, I am learning about Forex and am currently in preschool training I am stuck on the first section about pips. I know what a pip is, but i am struggling with the calculations. I am not understanding how they arrived to the final calculation. [(.0001 CAD) / (1.0200 CAD)] x 1 USD = 0.00009804
.0001 cad divided by 1.0200 cad X 1 usd = 0.00009804 how?

For the purpose of better explaining the calculations, exchange rates will be expressed as a ratio (i.e., EUR/USD at 1.2500 will be written as “1 EUR/ 1.2500 USD”)

Example exchange rate ratio: USD/CAD = 1.0200. To be read as 1 USD to 1.0200 CAD (or 1 USD/1.0200 CAD)

(The value change in counter currency) times the exchange rate ratio = pip value (in terms of the base currency)

[.0001 CAD] x [1 USD/1.0200 CAD]

Or Simply

[(.0001 CAD) / (1.0200 CAD)] x 1 USD = 0.00009804 USD per unit traded
