What is the purpose of using decimals rather than fractions as a whole?

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.

how Do you determine the least to greatest when using fractions and decimals?
You determine the least to greatest in decimals by using their leftmost unit. The decimal 0.2 is less than 0.3. To determine fractions, you need to first convert them to decimals.
Why converting decimals to fractions using number line is difficult?
Because some decimal numbers can't be converted into fractions if they are irrational numbers.
Can fractions be changed into decimals using roman numerals if so how?
No, fractions cannot be changed into decimals using Roman numerals. Roman numerals are a numeral system used in ancient Rome, which does not have a way to represent fractions or decimal numbers. Decimal numbers are represented using a base-10 system with digits ranging from 0 to 9.
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.
