mixed numerals and improper fractions
summary
mastering the conversion between mixed numerals and improper fractions is crucial for efficiently solving gmat math problems, especially in operations involving multiplication, division, and exponentiation.
- improper fractions have numerators larger than denominators, while mixed numerals combine an integer with a fraction less than 1.
- converting between these forms is essential, as the gmat may present numbers in either format.
- mixed numerals are useful for visualizing fractions on a number line, but are less effective for calculations.
- improper fractions are preferred for operations such as multiplication, division, and raising to powers due to their simplicity in calculations.
- when faced with mixed numerals in problems, converting them to improper fractions before calculating can simplify the process and reduce errors.
