Chapter 2: Fractions and Decimals
Fractions:
Fractions are a way of representing parts of a whole. In a fraction, the number on the top is called the numerator, and the number at the bottom is called the denominator. For example, in the fraction 3/4, 3 is the numerator and 4 is the denominator. Fractions can be added, subtracted, multiplied, and divided just like whole numbers.
Decimals:
Decimals are another way of representing parts of a whole, but in a more precise manner. Decimals are written in the form of a whole number followed by a decimal point and then the decimal part. For example, 0.75 is a decimal where 0 is the whole number part and .75 is the decimal part. Decimals can also be added, subtracted, multiplied, and divided just like whole numbers and fractions.
