multiplication is the Inverse operationof division so it could be used to check my work
Multiplication
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.

You don't. You can check addition with subtraction or subtraction with addition, since subtraction is the opposite of addition. Similary, you can check division with multiplication, or vice versa.

Multiplication
so when you find your answer you can check it by using multiplication.
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.
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.

we can multiply the divisor & the quotient to find the dividend
I think they invented it to do bigger mathscales, and to check multiplication because they are inverse operations.
You could divide the answer into the larger number of the problem. The answer should be the remaining number (multiplicand).
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
