Stage 8 - Q8 - 5 marks
Find every three-decimal-place value strictly between -0.304 and -0.299.
Hint
A value closer to zero is greater when both numbers are negative.
Stage 8 - Q9 - 5 marks
A digit d makes both inequalities true: \(2.4d>2.46\) and \(2.d4<2.84\). Find all possible digits.
Hint
Compare the first differing digit in each inequality.
Stage 8 - Q10 - 5 marks
Use the digits 1, 2, 3, 4 exactly once to make two positive decimals of the form a.b and c.d. Find the smallest positive difference possible and justify it.
Hint
To minimise the difference, use adjacent units and oppose the tenths difference.
