Study Notes

Operations with Fractions

Fractions can be added, subtracted, multiplied, and divided.

Essential Property of Fractions

The essential property of fractions is that the value of the fraction remains the same when both the numerator and denominator are multiplied or divided by the same nonzero number.

Invalid Operation

Division by zero is not a valid operation in fractions, or any other mathematical operation.

Multiplying Numerator & Denominator

Multiplying both the numerator and denominator of a fraction by the same nonzero number results in an equivalent fraction. The equivalent fraction represents the same value as the original fraction.

Purpose of Simplifying Fractions

When simplifying a fraction, dividing both the numerator and denominator by their greatest common divisor reduces the fraction to its simplest form. This simplified form is equivalent to the original fraction but is expressed with the smallest possible integers.
