## Listing Fractions and Decimals in Order

 Listing Fractions and Decimals in Order is a common question in the AQE and the GL tests. It requires the candidate to understand equivalent forms of fractions or decimals. Often, these can be both considered as percentages to quickly answer this question.

## Edges in a pyramid

 A common problem in the NI transfer tests is one that describes a 3-d shape in words, and asks how many faces / vertices / edges it has. I discovered that my son was answering these questions by sketching out the 3d shape - this inevitably led to a bad drawing and often to an incorrect answer. In some schools this is taught as an activity with midget gems and cocktail sticks so I gave that a try and it really helped. And we got to eat sweets - a great way to spend an hour on a rainy day.

## Ratio Questions in PPTC (GL)

 Ratios are a useful way of expressing the proportion of quantities in a mix, without having to specify the entire quantity. So if I’m making ham and cheese sandwiches (with one slice of ham and one of cheese per sandwich) I will require two slices of bread for every one slice of ham and one slice of cheese. I need slices of ham, cheese and bread in the ratio 1:1:2 – and that ratio never changes regardless of the total number of sandwiches required. Typically in questions, you will be given an original amount that must be split into a given ratio.

### An adverb is a word that modifies a verb, adjective, other adverb, or an entire sentence.

Most commonly they describe verbs (in a simialr way to an adjective describing a noun).

They often, but not always, end with -ly.

## Prime Numbers

 Prime Numbers are like phone numbers - there is no real pattern to them and you can easily look them up.  One of Einstein's colleagues asked him for his telephone number one day. Einstein reached for a telephone directory and looked it up. "You don't remember your own number?" the man asked, startled. "No," Einstein answered. "Why should I memorize something I can so easily get from a book?" However, to quickly complete some transfer test questions, you need to be able to recall the first few prime numbers quickly - and you won't be allowed books in to the exam!
