The distributive property is not used for simplified multiplication. See http://www.algebrahelp.com/lessons/simplifying/distribution for information about how to use the distributive property to simplify other equations. 20 x 12 is already simplified, so the proper way to solve it is 12

You could potentially factor and use the commutative property to find a simpler equation, ex.
20x12 -- break 20 into 10 and 2
10x2x12 -- multiply 2 by 12
10x24 -- multiply by 10

Multiplication can be the first step when using the distributive property with subtraction. The distributive law of multiplication over subtraction is that the difference of the subtraction problem and then multiply, or multiply each individual products and then find the difference.
7*9 = 9*(10 - 3) = 90 - 27 = 63
5*43 = 5*(40 + 3) = 5*40 + 5*3 = 200 + 15 = 215
you would go: (30x9) + (7x9) = 270 + 63 = 333 which is the same as if you typed 37x9 into the calculator and got 333!
Multiplicative identity property
First, I would find that the GCF of 20 and 16 is 4. Then, I would divide both 20 and 16 by 4. Last, I would use the distributive property to write the sum as 4(5 + 4).
Some people use the distributive property to add 24 and 36, but you wouldn't use it to find the GCF which, by the way, is 12.

6 x 4.3 = 6 x 4 + 6 x 0.3 = 24 + 1.8 = 25.8

The distributive property is not related to finding equivalent fractions. The distributive property is a rule that states a(b + c) is equal to ab + ac. It is used to simplify expressions and perform operations like multiplication or addition. To find an equivalent fraction, you would need to multiply or divide the numerator and denominator by the same nonzero number.
Multiplication can be the first step when using the distributive property with subtraction. The distributive law of multiplication over subtraction is that the difference of the subtraction problem and then multiply, or multiply each individual products and then find the difference.
You need at least two numbers to find a GCF.
(2 x 9) + (3 x 9) = 5 x 9 = 45 The GCF is 9.
You don't need to use the distributive property. 3*17 = 51 so 30*17 = 510 Why invoke procedures that are not necessary?
