How can I distinguish a fraction from a decimal number?
Both of the above are methods used to depict a specific number. You can distinguish the two by thinking of a fraction as the method that has two levels (i.e. 1/2) and the decimal number as the one that has a dot within that number(i.e. 0.5).
What does 'Diminishing Marginal Utility' mean?
Imagine you are very hungry and you are passing by McDonalds. You go in and order 4 BigMacs. You eat the first one. Because you have been starving, you enjoy this A LOT. You go on to eat the second one. You still enjoy this but not so much since you've already eaten one burger. Then you eat the 3rd one. The taste is still satisfactory but because you no longer have the same appetite your enjoyment is not as much. Then eating the 4th one is giving you minimal satisfaction (maybe a stomach ache as well, oops). And this is what 'Diminishing Marginal Utility' means. The more you consume a good or a service the less satisfaction you'll get from it.
What is a top tip to do well in Algebra?
Just remember to flip the sign every time you transfer your unknown on the other side of the equation. Quite simple but if you just remember this you're half way there to win the battle. Oh yeah, practice as well.
