Hi there!
I am sorry to hear you're having trouble with your homework. Good thing is we can help you and your sister! :D
Can you please send us a picture of your homework? To do so, you need to click on the image icon (square with moutains) at the bottom left of the question.
If that is impossible for you to do, you may explain what is your homework so we can guide you through it. :D
See you soon! :D
