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.
