Question

XXIX in hindu arabic numerals,please write with steps​

Answer 1

Answer:

29

Step-by-step explanation:

In this question it is given that we have to write ‘XXIX’ in Hindu-Arabic numerals. So for this we need to know that the symbol X = 10 and I = 1 also we need to know some rules to transform Roman numerals to Hindu-Arabic numerals, so the rules are:

1. If a smaller symbol is written to the right of a symbol with greater value, then its value gets added to the value of the greater symbol. For example, XI=10 +1= 11

2. If a smaller symbol is written on the left of a symbol with greater value, then its value is subtracted from the value of the greater symbol. IV= 5-1=4, IX =10-1 = 9 etc.

Complete step-by-step answer:

Here the given Roman numeral is XXIX

So by the above rules we can say that, initially X is repeated once so we have to add them i.e XX= 10+10 = 20, (by rule number 3)

Now as we know that IX = 10-1 =9 (by rule number 2)

Now in XXIX, IX is written to the right side of XX so we have to add them, so by rule (1) we can write,

XXIV = 20+9 = 29.

Note: While putting the values of Roman symbols, you need to know that if a symbol is repeated then its value is added as many times as it occurs. For example, II=2, XX=20 etc. but the restriction is, you cannot repeat a symbol more than three times.

hope it's helpful to you!

Answer 2

Answer:

XXIX in Arabic denotes the number 29

Step-by-step explanation:

Roman Numbers :

They are basically symbols used for denoting the normal digits such as 1, 2, 3, 4, 5,....... and they are represented by I, II, III, IV, V, VI, VII, VIII ,...

We know that X denotes  Arabic number 10

and I denotes  Arabic number  1

So when we write XX it denotes 10 + 10 = 20

and when we write IX it denotes = 9

So IX comes from X subtracted by I = X - I  = 10 - 1 = 9

Therefore, XX denotes 20 and IX denotes 9

So, XXIX denotes 20 + 9 = 29

Therefore, the required answer is 29
