Ready to tackle decimals? You'll be amazed at how easy they are to understand when you use grids and number lines. Once you know how to place decimals to tenths and hundredths place on the number line, you'll learn how to compare them and write decimals as fractions.
To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.
Put on your math detective hat and dive into this unit on decimal place value. You'll learn how to locate decimals on a number line, see which ones are bigger or smaller, and round them to the nearest whole number.
Place value and decimals are related. We can begin by reviewing the concept of ones, tens, and hundreds places, and then demonstrates how tenths, hundredths, and thousandths places work. By understanding place value, we can interpret the meaning of each digit in a decimal number.
Learn a technique for converting decimal numbers into binary numbers using just pen, paper, and calculations. Works best for small numbers, since bigger numbers require increasingly more calculations.
