Answer 1

Answer:

Step-by-step explanation:

1. VC

2. IL

3. VVII

4. IXX

Now we need to show that each of the given Roman Numbers are meaningless.

So in the first case we have VC

Now in terms of subtraction in Roman numerals, like X, C, I are subtracted but not V or L. Also the numeral V does not appear in front of a greater value that is C = 100

So 95 is XCV and not VC

In the next number we have IL

Here subtraction with a numeral less than 1/10th of the value to its right is not there.

I will be subtracted from V and X. So 49 is written as XLIX.

So from third case we have VVII.

Here some symbols can be repeated in a row up to 3 times but the number V may not be repeated. So we can write this as XVII = 17

So in the fourth case we have IXX

Here the lower value IX = 9 may not come in front of a greater numeral X = 10 and IX cannot occur to the left.

So we can write this as XIX = 19
