Decimals and Place Value

Practice exact addition, subtraction, multiplication and division of fractions, including signs and simplification. Questions, answer keys and explanations are written by Questena. The round score is accuracy on this practice set, not a pass/fail result, mastery claim, official result or prediction.

Practise school geometry — angle facts, triangle and quadrilateral types, perimeter, area, compound shapes, circle measures, solids and volume, metric unit conversions, coordinates and symmetry, all in fully text-described problems. The score reports correct answers in this round, not overall mathematics ability.

Practise integers and negative numbers — the number line, comparing and ordering, absolute value, the four operations with signs, real-world temperature, altitude and money problems, order of operations, four-quadrant coordinates and sequences crossing zero. The score reports correct answers in this round, not overall mathematics ability.

Practise percentages end to end — conversions with fractions and decimals, percent of an amount, percent change, reverse percentages, successive changes, percentage points, and money problems with discounts, tax and simple interest. The score reports correct answers in this round, not overall maths ability.

Practise ratios and proportional reasoning — notation and simplifying, ratios as fractions, sharing in a ratio, unit rates and best buys, direct and inverse proportion, recipe scaling, scale drawings, and judging what is proportional. The score reports correct answers in this round, not overall maths ability.

Read values, compare categories, and spot trends in bar charts, line charts, and data tables, and decide whether a stated conclusion is supported by the displayed data. The score reports correct answers in this round, not overall data interpretation ability.

Practise school statistics and probability — mean, median, mode and range, choosing an average, frequency tables, the probability scale, single events and complements, sample spaces and expected frequency. The score reports correct answers in this round, not overall mathematics ability.
