When life hands you “4 and 1/4,” don’t panic. Write it as 4.25 and move on with your day. You now possess a superpower: you can order 4.25 pizzas at a party, measure 4.25 inches of rope, and even calculate 4.25% of a tip (okay, don’t do that last one—your waiter will throw a napkin at you).
And if anyone asks, “What is 4 and 1/4 as a decimal?” you can just smile, sip your coffee, and say, “It’s 4.25, obviously. Now pass the sugar—I’ve got a quarter-cup to measure.”
End of story. No more fractions required. Unless you’re baking. Then good luck with the 1/3 cup.
