The Borrower (Not a Stealer)
Imagine you're at the fraction market, eager to buy a slice of delicious pie. The price? A cool ¾ of a pie. You only have ½ of a pie, though. What do you do? Panic? Sell your prized yo-yo collection (don't do that, it's sentimental)?
Nope! This is where the art of borrowing comes in. You simply borrow 1 whole pie from the friendly baker (don't worry, you'll pay him back later). But remember, you can't just take a whole pie and shove it in your fraction pocket. You gotta be sneaky, mathematically sneaky that is.
Tip: Review key points when done.
The Great Transformation: From Whole to Fraction
Since you borrowed a whole pie, you need to convert it into a fraction with the same denominator as the price of the pie (¾ in this case). So, how many ¾s are in 1 whole pie? Think of it like cutting the whole pie into ¾ slices! You end up with 4 pieces, each being ¾ of a pie.
The Grand Payoff: Subtraction Showtime!
Now comes the satisfying part: paying back the baker (mathematically, of course). Add the borrowed 4/3 to your original ½:
QuickTip: Focus more on the ‘how’ than the ‘what’.
½ + 4/3 = (3/6) + (4/6) = 7/6

Now, you have 7/6 of a pie, which is more than enough to pay for the delicious slice (¾). Finally, subtract the original price from your newly acquired pie:
Tip: Read at your natural pace.
7/6 - ¾ = (7/6) - (3/6) = 4/6
Voila! You've successfully navigated the fraction market, bought your pie, and even returned the borrowed pie (mathematically speaking).
QuickTip: Repeat difficult lines until they’re clear.
Remember: Borrowing in fractions is all about keeping things equal and having the right tools (fractions with the same denominator) for the job. So, the next time you encounter a subtraction problem that seems impossible, remember, with a little borrowing magic, you can conquer any fraction challenge!
