Roman Numerals all Questions Solution :
Question no – (1)
Solution :
Here we have to write numbers 1 to 20 in Roman numerals. For this we have to know basic symbols which are used in Roman numerals.
For 1 we write as I
For 5 we write as V
For 10 we write as X
Now, we write numbers 1 to 20 in Roman numerals.
- 1 = I
- 2 = II
- 3 = III
- 4 = IV
- 5 = V
- 6 = VI
- 7 = VII
- 8 = VIII
- 9 = IX
- 10 = X
- 11 = XI
- 12 = XII
- 13 = XIII
- 14 = XIV
- 15 = XV
- 16 = XVI
- 17 = XVII
- 18 = XVIII
- 19 = XIX
- 20 = XX
Question no – (2)
Solution :
(1) V
Here we have to write Roman numerals in number form.
We know,
V = 5
(2) VII
Here we have to write Roman numerals in number form.
We know,
V = 5
I = 1
VII = V + I + I
VII = 5 + 1 + 1
VII = 7
(3) X
Here we have to write Roman numerals in number form.
We know,
X = 10
(4) XIII
Here we have to write Roman numerals in number form.
We know,
X = 10
I = 1
XIII = X + I + I + I
XIII = 10 + 1 + 1 + 1
XIII = 13
(5) XIV
Here we have to write Roman numerals in number form.
We know,
X = 10
V = 5
I = 1
XIV = (X + V) – I
XIV = (10 + 5) – 1
XIV = 14
(6) XVI
Here we have to write Roman numerals in number form.
We know,
X = 10
V = 5
I = 1
XVI = X + V + I
XVI = 10 + 5 +1
XVI = 16
(7) XVIII
Here we have to write Roman numerals in number form.
We know,
X = 10
V = 5
I = 1
XVIII = X + V + I + I+ I
XVIII = 10 + 5 +1+1+1
XVIII = 18
(8) IX
Here we have to write Roman numerals in number form.
We know,
X = 10
I = 1
IX = X – I
IX = 10 – 1
IX = 9
Question no – (3)
Solution :
(i) We have to write 3 in roman numerals.
We know,
I = 1
3 = I + I + I
3 = III
(ii) We have to write VIII in number form.
We know,
V = 5
I = 1
VIII = V + I + I + I
VIII = 5 + 1 + 1 + 1
VIII = 8
(iii) We have to write 6 in roman numerals.
We know,
V = 5
I = 1
VI = V + I
VI = 5 + 1
VI = 6
(iv) We have to write XII in number form.
We know,
X = 10
I = 1
XII = X + I + I
XII = 10 + 1 + 1
XII = 12
(v) We have to write 15 in roman numerals.
We know,
X = 10
V = 5
XV = X + V
XV = 10 + 5
XV = 15
(vi) We have to write XIX in number form.
We know,
X = 10
I = 1
XIX =(X + X) – I
XIX = (10 + 10) – 1
XIX = 20 – 1
XIX = 19
| Number | Three | 8 | Six | 12 | Fifteen | 19 |
| Roman number | III | VIII | VI | XII | XV | XIX |
Question no – (4)
Solution :
(1) 9 = IX
(2) 2 = II
(3) 17 = XVII
(4) 4 = IV
(5) 11 = XI
(6) 18 = XVIII
Question no – (5)
Solution :
(i) 4 given in roman numerals is wrong.
We know,
V = 5
I = 1
4 we write as,
4 = 5 – 1
4 = V – I
4 = IV
(ii) 6 given in roman numerals is correct.
(iii) 8 given in roman numerals is wrong.
We know,
V = 5
I = 1
8 we write as,
8 = 5 + 1+ 1+ 1
8 = V + I+ I+ I
8 = VIII
(iv)16 given in roman numerals is correct.
(v) 15 given in roman numerals is wrong.
We know,
X = 10
V = 5
15 we write as
15 = 10 + 5
15 = XV
