denominator · The denominator is the bottom number. It shows how many equal parts make the whole.
90 cm · The unit comes after the number: 90 cm tells us exactly what was measured.
True · The open side of > faces the 7, so the statement reads 7 is greater than 3.
2 · The numerator is the number of shaded parts you have: 2.
Tom's · Tom's answer includes the unit, metres, so we know exactly what he measured.
£3.20 · Money uses the £ sign before the number and a decimal point, like £3.20.
equivalent · Equivalent fractions have different numbers but stand for the same amount.
She forgot to include the units · Without a unit like cm, nobody knows if 120 means centimetres or something else.
