Forward contract lecture

Hello Sir
Lecture forward cotracts
I understand in exp 3 because x is buying first currency $200,000
so we devide $200000/1.4910

I didnot understand in exp 4 why we multiplying
i know y is receiving and that mean y will sell $ to convert in £
because selling choose 1.5334
now my query is when we buy we devide and when we sell we multiply
Why in this example we deviding inthe place of multiply
