Чтобы найти делитель, надо делимое разделить на частное. 

Answer 2

The expression "21840:х=52" means "21840 divided by x equals 52". To solve for x, we can cross-multiply to get:

21840 = 52 * x

Then we can divide both sides by 52 to isolate x:

x = 21840 / 52

Performing the division gives:

x = 420

Therefore, the solution to the equation "21840:х=52" is "x=420". The "знак" symbol in between the numbers is the division symbol (÷).
