Page 1: Introduction to Percentage Calculations

This page introduces the fundamental concepts of increasing and decreasing values using percentages and fractions. The content focuses on teaching the multiplier method for percentage calculations.

Definition: The multiplier method converts percentage changes into decimal numbers for easier calculation.

Example: To increase by 7%, add 100% + 7% = 107%, then convert to 1.07 as the multiplier.

Highlight: When decreasing values, subtract the percentage from 100% to find the correct multiplier.

Vocabulary: A multiplier is a decimal number used to calculate percentage changes in a single step.

The page demonstrates various calculations including increasing £150 by 7%, £200 by 50%, and $4.80 by 1%, as well as decreasing 5.72kg by 2%, 80 by 20%, and 240 by 0.5%.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
