She spent $23.25, how I got my answer.
I divided $13.50÷2=$6.75 then I added $6.75+3=$9.75 then I added $9.75+$13.50=$23.25.
I hope this helps.
If he won 40, then he lost 112-40 or 72 games.
Ratio= lost/win
Ratio=72/40
72/40
Hope this helps :)
Would it be a ratio, if it is it would most practically be 10:40 and if in simplest form it would be 1:4 or just you photo math
