FRACTIONS and DECIMALS
Fractions and decimals are both ways to represent numbers that are not whole numbers. A fraction
expresses a part of a whole using a numerator (top number) and a denominator (bottom number), while a
decimal uses a decimal point to separate the whole number part from the fractional part. They represent
the same value but in different formats.
Fractions:
A fraction like 1/2 represents one out of two equal parts of a whole.
The top number (numerator) indicates the number of parts you have, and the bottom number
(denominator) indicates the total number of parts the whole is divided into.
Fractions can be proper (numerator smaller than denominator), improper (numerator larger than
denominator), or mixed numbers (whole number and a proper fraction).
Decimals:
A decimal like 0.5 also represents one half.
The digit to the right of the decimal point represents tenths, hundredths, thousandths, and so on.
Decimals are based on powers of 10, making them convenient for calculations, especially with the metric
system.
Converting Between Fractions and Decimals:
To convert a fraction to a decimal, divide the numerator by the denominator. For example, 1/4 is 1 divided
by 4, which equals 0.25.
To convert a decimal to a fraction, you need to determine the place value of the last digit (tenths,
hundredths, etc.) and write it as a fraction with that denominator. Then, simplify the fraction if
possible. For example, 0.75 can be written as 75/100, which simplifies to 3/4.
Relationship:
Fractions and decimals are different ways of expressing the same numerical value.
For example, 1/2, 0.5, and 50% all represent the same quantity.
Understanding both fractions and decimals is essential for various mathematical operations and real-
world applications, like currency conversions.
