Is there a calculator that can calculate fractions?

Answer 1

Absolutely! Today's calculators do far more than the early ones that only performed the basic operations of addition, subtraction, multiplication, and division. Most scientific calculators today have a Fraction Key which I will denote FK for this post.

For example, on the TI-30Xa, the FK is denoted a b/c which corresponds to a mixed number such as 3 1/2. There's also an improper fraction key denoted d/c which can be accessed using the 2ndfunction key. Regardless, I've found that the a b/ckey will suffice for any fraction (regular, improper, and mixed).

Entering fractions into the calculator is easy. Suppose you wanted to evaluate the following: 2 1/3 + 7/8. Enter "2 FK 1 FK 3 + 7 FK 8 =" Presto! Your answer appears in a format similar to the following "3_5_24" which represents 3 5/24.

No more having to find common denominators! The fraction key also works with the other basic operations of subtraction, multiplication, and division. Did I mention that it also reduces the answer to it's simplest form?

That Fraction Key is what I call amazing!
