Yes. the number is 0.2 (or the equivalent 1/5).

That word "equals" in there makes it an equation.
That equation has no solution. There is no possible number that's equal to 18 more than itself.
To find the number that, when divided by 2, equals 14, you can set up the equation ( x/2 = 14 ). By multiplying both sides by 2, you get ( x = 28 ). Thus, 28 divided by 2 equals 14.
To find the number for which one fifth equals 18, you can set up the equation ( \frac{1}{5} \times x = 18 ). Multiplying both sides by 5 gives ( x = 90 ). Therefore, the number is 90.
When you multiply both sides by a negative number the inequality must be flipped over. You do not do that when multiplying by a positive number.

You can remove parenthesis or bracket by multiplying the number outside, with the number inside the bracket.
To find the number for which one fifth equals 18, you can set up the equation ( \frac{1}{5} \times x = 18 ). Multiplying both sides by 5 gives ( x = 90 ). Therefore, the number is 90.
That means that multiplying both sides of the equation by the same non-zero number is a valid operation, which often helps you simplify the equation.
In general, if you apply the same operation to both sides of an equation, you get an equivalent equation - at least if you do simple things like adding, subtracting, multiplying by a non-zero number, and dividing by some number.
Multiplying a number by its inverse equals a * (1/a) = 1. The a cancels out.
