multiply by 100, therefore in the case of 0.125 the equivalent percentage would be 12.5%.

Hello, Janet!

How to write a decimal, i.e., 0.125 as a percentage

Move the decimal point two places to the*right*... and append "%".

Hence: .$\displaystyle 0.125 \quad\Rightarrow\quad 12.5\%$

I think of the % symbol as being a constant of .01 or 1/100. This way 100% = 100 x .01 = 1 and .125 = 12.5 x .01 = 12.5%. I don't know if this is a helpful way to learn it the first time but it makes a lot of sense after learning implied multiplication.
