Multiplication is a very old concept in math. So old that it dates back to ancient egypt, mesopotamia, etc. Each place probably came up with the concept on their own parallel to one another, or trade helped make the concept spread. It's very likely that the actual person who came up with the idea is unknown and won't be known since the concept is so ancient. It's like asking "who came up with the alphabet" which is an equally old concept.
Side note: multiplication is repeated addition. So if we added 3+3+3+3+3 to get 15, then we can say 3*5 = 12 as a shortcut. So its likely ancient peoples were adding the same number to itself over and over, leading them to develop a shortcut notation/method to get the answer quicker.

Answer:
Option C.
Step-by-step explanation:
Let as consider parallel lines r and s are cut by transversal q. On line s where it intersects with line q, the uppercase left angle is 125 degrees and the bottom right angle is d degrees.
We need to find the value of d.
If a tranversal line intersect two parallel lines, then the alternate exterior angles are equal.
Uppercase left angle and bottom right angle are alternate exterior angles. So we can say that
d = 125°
Therefore, the correct option is C.
The ratio of 36 to 27 is 4:3
