### if you have 2.5 pints and you add .5 cups how much do you have

Depends where in the world you are and how big your cup is.

Recipes were designed to use cups as a measure because as long as the same cup was used the proportions remained the same regardless of the cup size and each recipe could be followed exactly.

Interfering busybodies ruined a perfectly good system by deciding a cup should be approximately half a pint or 8 fluid ounces, a good deal larger than the average teacup and as you will see in the chart of new-fangled measures below, they decided a teacup is actually half a cup...

I think you should now be equipped to answer your own question...
