It is usually applied in arithmetic to simplify multiplication.
For example, find the value of 9*46.
Now, my knowledge of the 9 times table does not extend to 46 nines and I certainly do not know the 46 times table but, using the distributive property:
9 * 46 = 9*(40 + 6)
= 9*40 + 9*6 [That's the step where the distributive property was used]
and, now its easy. I know 9*4 = 36 so 9*40 = 360 and 9*6 = 56
Thus 9 * 46 = 360 + 56 = 416.
No.
No, it is not.
Multiplying decimals is similar to multiplying whole numbers in that the same multiplication rules apply, such as the distributive property and the arrangement of numbers. The key difference lies in the placement of the decimal point in the product; after multiplying, you count the total number of decimal places in the factors and place the decimal point in the product accordingly. This ensures that the value of the result accurately reflects the decimal nature of the original numbers.
The distributive property combines addition and multiplication, allowing you to break down larger numbers into smaller, more manageable parts. For example, instead of calculating (7 \times 26) directly, you can use (7 \times (20 + 6)) to simplify the process to (7 \times 20 + 7 \times 6), making the multiplication easier. This property helps in mental math and simplifies calculations, particularly with larger numbers.
Similarities: the sum does not depend on which number you start with (distributive)Differences: you must find a common denominator for the fractions (whole numbers have a common denominator [1]
The distributive property combines addition and multiplication to make multiplying whole numbers easier. This property states that for any three numbers a, b, and c, a x (b + c) = a x b + a x c. By applying the distributive property, we can break down complex multiplication problems into simpler steps, ultimately making calculations more manageable and efficient.

The distributive property is important because it combines both addition and multiplication. This property states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. For example:3(2 + 5) = 3 x 2 + 3 x 53(7) = 6 + 1521 = 21if we let a, b, and c be any whole numbers, thena(b + c) = ab + ac

No it is not an associative property.
yes
Both.
yes
Factors apply to whole numbers, not decimals.
