For example, you can do the multiplication in both cases, simplify each product to simplest terms, and compare. Or, after doing the multiplication, check the product of the numerator of one fraction by the denominator of another fraction - if you get the same product both ways, the products are equivalent.
It is not: they are the same. A "product" and "multiple" are synonyms.
The meaning of dissimilar fractions is when there is a pair or more of fractions that don't have the same denominator.
Exactly the same as you do when multiplying fractions with different denominators. -- Multiply numerators . . . the product is the numeratore of the answer. -- Multiply denominators . . . the product is the denominator of the answer.
No. Fractions don't need the same denominator in order to multiply them. The numerator of their product is simply the product of their numerators, and the denominator of their product is just the product of their denominators.
Fractions are integers when their denominator is 1 or when the numerator has the same value as the denominator.
A square number
You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.
They have the same parity (odd or even).
Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
Yes, then do the same for the denominators. But THEN you are usually expected to simplify the resulting fraction.
If you are dividing the numerator and the denominator by the same number (the GCF), it is the same as dividing the fraction by 1, which will leave it unchanged and create the same product.
