Lets try this one last time

What is the value for the numerals with letters:
245,189

2=a
5=b
8=c

I'm not sure what you are asking. (That is probably the reason why you are not getting responses.) Try explaining the problem in more detail.

To determine the value of the given numerals with the assigned letters, we can substitute the letters with their corresponding values:

245,189

Using the given assignments:

2=a
4=?
5=b
8=c
9=?

Since the value of the numeral with the letter 'a' is 2, we know that the numeral 2 represents the letter 'a'.

So, we can rewrite the numerals as:

a45,1a9

Now, we need to determine the values of the remaining letters 'b' and 'c' and the numeral 4 and 9.

Unfortunately, without further information or additional assignments, we cannot determine the specific values for 'b', 'c', 4, and 9. The provided assignments only allow us to substitute the value for 2, represented by the letter 'a', and 5, represented by the letter 'b'.

If there are any additional assignments or information, please provide them so we can determine the values accordingly.
