All answers should be provided without the units, but attention must be paid to the unit instructions in each question. For example, if your answer is 100.3 W/m2K, type 100.3 only.

All answers must be rounded to one digit, unless otherwise stated. For example, if your answer is 100.27, type 100.3.

Written for the Western Sydney University MESH numeracy preparation workshop for the LANTITE test (Australia). Students are given a height in centimetres and another height in metres, and are asked to write the ratio of the two heights in simplest form. There are 16 versions of this question.

Twenty questions which can be used by Initial Teacher Education students preparing for the Australian LANTITE numeracy test. The questions are grouped in content strands and each question is randomised. Questions are either multiple choice, true/false or type the answer in a box. The questions are chosen from a menu and there is no time limit. They are different to the questions in Timed Practice Quiz v2.

This practice quiz contains 40 numeracy questions, for students preparing for the Australian LANTITE numeracy test. Each question is randomised.

There are 10 questions each from the Number and Algebra, Measurement and Geometry, Statistics and Probability, and non-Calculator strands.

Students are allowed 75 minutes to complete the test. The questions are multiple choice, true/false or fill the number in the box.

Used for LANTITE preparation (Australia). MG = Measurement & Geometry strand. Student must convert the time shown on the analog clock to 24 hour time. One of six analog clock images is randomly selected and displayed.

Simplifying expressions from $\frac{x^mx^n}{x^p}$ to $x^{m+n-p}$. 

Fractions already have a common denominator. Addition and subtraction 50:50 split, when subtracting, the answer is negative half the time. Students shouldn't have to worry about reducing fractions by design.

Here you need to choose which formula you would use to find the red dashed value from the solid green values.  The view is three-dimensional and you can rotate it to get a better view.

Variable defintions in the formulas:
$\theta$ is an angle
Adj. is the length of the side adjacent to the known angle
Opp. is the length of the side opposite the known angle
Hyp. is the length of the hypotenuse
