once x cien = mil cien

once x cien = Mil ciento

which on is right??

The second one. Ciento is only shortened to "cien" before a larger number or a noun, such as "cien hombres" = 100 men.

To determine which statement is correct, we need to analyze the two equations:

1) Once x cien = mil cien
2) Once x cien = mil ciento

Both statements involve multiplication, with "x" being a placeholder for a number. Let's break down each equation separately:

1) Once x cien = mil cien
In this equation, "Once" represents 11, and "cien" represents 100. Therefore, the equation translates to:
11 x 100 = 1,100

2) Once x cien = mil ciento
Here, "Once" still represents 11, but "ciento" represents 100. "Mil ciento" translates to 1,100. Thus, the equation translates to:
11 x 100 = 1,100

After analyzing both equations, we can conclude that they are actually equivalent, which means they are both correct. Both expressions represent the same multiplication, resulting in the value 1,100.

Therefore, both equations are right.
