Composite digits to prime digits in 638,527

Would this be No

No, it would not be No.

The primes are 2,3,5,7
So, there are 4 primes and 2 composites.
The ratio is 2:4 = 1:2

To determine whether the composite digits (non-prime digits) in the number 638,527 can be converted into prime digits, we first need to identify the composite digits in the number.

Composite numbers are numbers that have more than two positive divisors. The prime numbers, on the other hand, are numbers that have exactly two positive divisors: 1 and the number itself.

Now let's break down the number 638,527:

The composite digits in this number are:
6 (composite)
8 (composite)

The prime digits in this number are:
3 (prime)
5 (prime)
2 (prime)
7 (prime)

Since the composite digits (6 and 8) cannot be converted into prime digits, we can conclude that it is not possible to transform all the composite digits in the number 638,527 into prime digits. Therefore, the answer to your question would be "No."
