Answer:

30% also means 30/100 in fraction form.

(Think of the root 'per' in percent to be per a 100.)

The keyword 'of' means multiplication.

'X' will be the unknown number aka the part that says ('-what number').

And 123 will represent the result.

Set up equation;

30/100 · x = 123

Then solve for x;

30/100x = 123

0.3x = 123

÷ 0.3 ÷ 0.3

x = 410

So your answer is 410.
