Different numeric bases have advantages over each other. For example, there is a known equation that can be used to calculate the nth digit of pi, but only in hexadecimal.
The main reason for using different bases in the modern world is the use of computers. Consider the way computers work - everything is an on-off switch. It can have two states, on or off, which can be used to represent numbers, 1 or 0. This extends beautifully to binary math. With decimal math, we would need a switch that could hold ten different states, and that would be only for a single-digit decimal number.
Write 2 ways in which whole numbers and decimal numbers are different
The answer depends on the context. The process for changing bases in logarithms is different to that for representing numbers in different bases - although the two are closely related.
They are called roman numerals.

There are many different ways one might write the numbers '608.' If one desires to write the numbers '608' in Roman numerals, one would write 'DCVIII.'
Mainly when working with computers. Occasionally I've seen some olympiad-type problems that involve working with different bases.
You just wrote it in numbers.. but. 31,4207 is how you write it in numbers
10x5 and 1x50
There is no international form in words because different languages have different words for numbers.
Before you can do that, you need to write each mixed number as an improper fraction, and then write both fractions with a common denominator. The only other choice is to write both mixed numbers as decimals, and then add them.
You can write nine numbers: 125, 225, 325, 425, 525, 625, 725, 825, 925.
