- 1.Work out (4 × 10⁻³) × (2 × 10⁵). Give your answer in standard form.
- 2.A set of kitchen scales displays the mass of a bag of sugar as 0.63 recurring kilograms, meaning 0.636363... kg with the block '63' repeating forever. Convert this mass to a fraction of a kilogram, then work out the mass in grams, giving your answer to the nearest gram.
- 3.A charity raises money from a raffle and a cake sale in the ratio 5 : 3. Altogether the charity raises £320. Work out how much money the cake sale raised.
- 4.Work out an estimate for 6.4 × 3.9, by rounding each number to the nearest whole number.
- 5.Simplify x⁽³⁄⁴⁾ ÷ x⁽¹⁄⁴⁾
- 6.Given that 4³ = 64 and 5³ = 125, estimate ∛100 to 1 decimal place.
- 7.A charity bake sale sells 187 cakes at £2.95 each. By rounding each number to 1 significant figure, work out an estimate for the total amount raised.

- 10.Four students each estimate √70 without a calculator. Ben says: '8² = 64 and 9² = 81, and 70 is about a third of the way from 64 to 81, so √70 ≈ 8.3.' Chloe says: '8.5² = 72.25, which is close to 70 but a little too big, so I'll bring it down slightly to √70 ≈ 8.4.' Dan says: '9² = 81 is closer to 70 than 8² = 64 is, so √70 ≈ 8.9.' Ella says: '8² = 64 and 9² = 81, so I'll just take the midpoint of 8 and 9: √70 ≈ 8.5.' Given that √70 = 8.3666... to 4 decimal places, whose estimate is closest?
- 11.Work out 3 1/5 + 1 2/3. Give your answer as a mixed number in its simplest form.
