Use currency table to calculate rate to third currency

I have a table like the below

I'm trying without luck to create a calculated column that would take the monthly to gbp rate and divide it by the monthly rate for USD within the relevant month, trying to do this without the "Calculate" funtion as I know that can cause performance issues. This would allow me to get the direct conversion for each into USD.

My table has been simplified for this question. The actual table would contain rates for each day throughout a month.

@PBI-BOLA,

 

Try this calculated column:

 

GBP/USD Rate = 
VAR vStartingDate = 'Currency'[Starting_Date]
VAR vUSDRate =
    MAXX (
        FILTER (
            'Currency',
            'Currency'[Currency_Code] = "USD"
                && 'Currency'[Starting_Date] = vStartingDate
        ),
        'Currency'[Monthly Average Conversion Rate to GBP]
    )
VAR vResult =
    DIVIDE ( 'Currency'[Monthly Average Conversion Rate to GBP], vUSDRate )
RETURN
    vResult
