How to iterate through a hashtable of keys and compare against another hashtable in powershell

I have two PSCustom Objects / hashtables that contain license names and values for office 365. I am looking for a method to search the second hashtable for the matching license name so I can do some math to get percentage consumed of the total count for each Business unit.

• ConsumedLicenses

• LicenseCounts

I originally started on using a nestled foreach loop but found that will not do what I want to do. Looking for some guidance on how to proceed.

Foreach($consumedlicense in $ConsumedLicenses)
{
    $match = $true
    Foreach($licensecount in $LicenseCounts)
    {
        if($consumedlicense.keys -ne $licensecount.AccountSkuId)
            {
            Write-host "$consumedlicense.keys not $licensecount.AccountSkuId"
            $match = $false;Break
            }
    }
    if($match)
    {
    Write-host "$consumedlicense.keys matches $licensecount.AccountSkuId"
        $Percentage = $ConsumedLicense.values / $licensecount.ActiveUnits
        Write-Host "$consumedlicense.keys = $Percentage of total licenses."
    }
}
