Roman numeral rules

1. letters are never repeated, when a letter is repeated, its value is repeated. EX: 3= III 2. letters are never repeated more than three times, instead of repeating a number four times, subtraction is used. EX: 4 = IV 3. when a smaller number is placed in front of a larger number, it is subtracted. ( this is commonly seen with numbers ending in 4 (IV) or 9 (IX). 4. V, L, D can never be repeated and are never subtracted from a larger number 5. never subtract more than one numeral in a sequence. 6. when an equal or smaller number is placed after the larger number, it is added. EX: 15= XV 7. when there is three or more numerals AND a smaller valued numeral comes between two larger valued numerals, subtract the smaller valued numeral from the larger valued number that follows it. EX: 19= XIX

steps to solve a fraction multiplication problem

1. multiply the numerators to get a new numerator 2. multiply the denominators to get new denominator 3. use the new numerator and denominator to write the new fraction.
