I want to create an app that extracts percentages from a number

I want to create an application that extracts percentages from two numbers

What are the appropriate blocks?

Consider two numbers 30 and 45. Let us calculate what percentage is 30 out of 45.

For this, we divide the part (30) by the whole (45) and multiply the result by 100.

This gives 30/45 × 100 = 66.67%.

So, 30 is 66.67% of 45.

What blocks did you use for the project, can you explain

divide textbox1 value with textbox2 value and multiply by 100 that’s it

And how do I program the button to extract the result?

I want to add a rewarding Admob ad before extracting the result
