How do you test if the fraction are equivalent?
You can check by cross-multiplication. For example, to check whether 1/2 is equivalent to 3/6, multiply 1 x 6 = 6, and 2 x 3 = 6 (the numerator of each fraction with the denominator of the other fraction). Since in this case the results are equal, the two fractions are equivalent.

How do you know when a pair of fractions have the same product?
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.

How can you use multiplication to check a division problem?
we can multiply the divisor & the quotient to find the dividend
Why was division invented?
I think they invented it to do bigger mathscales, and to check multiplication because they are inverse operations.
How do you check multiplication using division?
You could divide the answer into the larger number of the problem. The answer should be the remaining number (multiplicand).
How are multiplication and division of whole numbers related?
Multiplication and division are opposites, therefore by multiplying/dividing, you can use the other one to check your answer. say 2x2=4. if you didnt know that for sure (which you should,) you could go like 4/2=2. that means they are related
