| \(\dfrac{2}{3}\) | P1 | for start of process to write down proportion of each coin, writes down a correct ratio, eg 1p : 2p = 2 : 1 oe or a process to work out number of 1p coins and 2p coins, eg \(40 \div 2\ (= 20)\) and \((40 \div 2) \div 2\ (= 10)\) or assigns numbers in correct proportion, eg 6 1p coins and 3 2p coins or finding the probability of a 2p coin \(\left(= \dfrac{1}{3}\right)\) |
| A1 | for \(\dfrac{2}{3}\) oe |
Additional guidance
Accept any equivalent fraction, decimal form, 0.66(6…) or 0.67 or percentage form, 66(.6…)% or 67%
