Decimals are easy to compare, add, subtract, multiply, and divide, because they already have a common denominator. You can tell at a glance which is bigger than which.

Further the SI, or metric-based, units are based on decimals and powers of 10, so any vulgar fractions in using them arise only when writing real values in a formula.

Name one advantage of decimals over fractions?

It depends on what you are trying to do. For most people using decimals is easier because it allows them to visualize the number better than a fraction. For example, if you needed to order them from least to greatest, it may be easier to see them in decimal form rather than fractions. However, fractions are usually more accurate because some decimals need to be rounded off. For example, the fraction 1/7 is more accurate than the decimal form .142857142857..... because the numbers 142857 continue on infinitely.

How do you use fractions with number lines?

well it is easy because you know how between every while nomber there is a decimal, like 0.5, and there are fractins, like 1/2. If you look at using decimals, then it is the same thing as using fractins because all decimals equal a fractin like 0.5 = 1/2 or .1 = 1/10, just replace deecimals with fractions and there you have it!
