multiple | any product of a given number; in a x b = c, c is a multiple of both a and b |
factor | any even divisor of a whole compound number; in a x b = c, a and b are factors of c |
numerator | how many parts we have of the whole; the top number in a fraction; in an "of" word problem, the numerator multiplies |
denominator | how many total pieces for this fraction; the bottom number in a fraction; in an "of" word problem, the denominator divides |
decimal_place | a digit showing how many times ten (to the left of the decimal point) or times one-tenth (to the right) |
decimal_point | to the left are whole numbers; to the right are how many parts of one whole |
percent | how many parts of one hundred in this fraction; a tenth is 10 percent; a half is 50 percent |
fraction_to_decimal | divide the numerator by the denominator |
decimal_to_fraction | state as a fraction with as numerator the given decimal and as denominator a one with as many zeros as digits in the decimal; simplify |
