Fraction and Decimal Word Problems

A fraction represents a part of a whole and is written as 'a/b', where 'a' is the numerator (part) and 'b' is the denominator (whole).

A decimal is a way of expressing fractions in a base-10 system, using a decimal point to separate the whole number from the fractional part.

To subtract fractions with different denominators, first find a common denominator, convert the fractions, and then subtract the numerators.

To convert a fraction to a decimal, divide the numerator by the denominator.

To add fractions with the same denominator, simply add the numerators and keep the denominator the same.

The least common multiple (LCM) is the smallest multiple that two or more numbers share.

To multiply fractions, multiply the numerators together and the denominators together.

A mixed number is a whole number combined with a proper fraction, such as 1 1/2.

To convert a mixed number to an improper fraction, multiply the whole number by the denominator, add the numerator, and place that over the original denominator.

A proper fraction has a numerator smaller than the denominator, while an improper fraction has a numerator larger than or equal to the denominator.
