Decimals and fractions are alike because all decimals are fractions and all fractions are decimals. As an example: 1/2, which is one-half, is the same as 0.5.
Fractions and decimals are similar because they both are ways to express partial numbers. Additionally, fractions can be expressed as decimals by performing the division of the ratio. Decimals can also be expressed as fractions in terms of tenths, hundredths, thousandths and so on. One main difference between fractions and decimals is that fractions tend to be simple expressions of ratios of whole numbers. They do not always divide into an easy-to-express decimal. Conversely, decimals can be used to describe long, complex and potentially infinite numbers, such as the value of pi. We can use fractions and decimals in everyday life because of money.
