Yes.
if both numbers are even you take them both dived by the number they both go into until you cant any more.
Yep, they can be negative too :)
Yes, it applies to even multiplication of fractions and rational and irrational numbers.
Every integer (whole numbers, including positives, negatives, and zero) is either odd or even. No number is both odd and even. Other numbers, such as fractions that don't reduce to an integer, irrational numbers, and pure imaginary numbers are neither odd nor even. Zero is an even number and is not an odd number.
The terms "odd" and "even" apply to integers (whole numbers), not to decimals or fractions.
both even numbers out of what you need to be more specific
No. Easy way to tell: the numerator and denominator are both even numbers therefore they can be divided by 2.
Even or odd is a property that only integers (the whole numbers, including positives, negatives, and zero) have. We do not call other numbers (fractions, irrational numbers, imaginary numbers, and so on) either even or odd.
The terms "even" and "odd" apply to whole numbers, not to decimals or fractions.
You can have algebraic fractions but, even there, the letters do represent numbers; except that their values are indeterminate.
There is no end to the numbers of maths and there are many classifications of numbers, like primes, fractions, even, odd, positive, negative and others.
At least one of the two numbers has to be even, but both can be even.
