Answer:
1) 90%
2)40%
3)75%
Step-by-step explanation:
the space between 2 lines are considered 10%. so let's take the first one for instance
1) as I said before, the space between 2 lines are considered 10%. So what you are going to use is the 10 times table (it will be a really helpful thing if you know all of the time table from 1 - 10) now what you do is count all the way from 0 till the blue thing ends. but If blue thing ends in the middle like in the picture number 3 then it's considered 5% since it's only halfway
I hope it was hopeful and that you understood
