Question

Is a negative decimal always sometimes or never equal to a positive decimal

Answer 1

Never. Negative numbers by definition are separate class from positive numbers, so negative decimals are never equal to positive numbers.

I hoped i help :)

Answer 2

It would never be equal because negative decimals and positive decimals are on either ends of the number line, negative is lass than 0 and positive is greater than 0. So they cannot be equal in any case.
