|---|---|---|
| 40 | P1 | for a process to find the maximum number of batches for one ingredient, eg \(500 \div 175\ (= 2.85...)\) or \(300 \div 75\ (= 4)\) or \(625 \div 250\ (= 2.5)\) OR for a process to find the amount of one ingredient for 1 biscuit, eg \(175 \div 16\ (= 10.9375)\) or \(75 \div 16\ (= 4.6875)\) or \(250 \div 16\ (= 15.625)\) OR for multiples of \(175 : 75 : 250\), eg \(175 \times 2\ (= 350)\) and \(75 \times 2\ (= 150)\) and \(250 \times 2\ (= 500)\) |
| P1 | (dep P1) identifies flour as the limiting factor OR for a process to find the maximum number of biscuits for one ingredient, eg butter: \(\text{``}2.85\text{''} \times 16\) or \(500 \div \text{``}10.9..\text{''}\) oe \((= 45.7...)\) sugar: \(\text{``}4\text{''} \times 16\) or \(300 \div \text{``}4.6..\text{''}\) oe \((= 64)\) flour: \(\text{``}2.5\text{''} \times 16\) or \(625 \div \text{``}15.625\text{''}\) oe \((= 40)\) | |
