4MA0 Higher June 2014 Paper 3 Q2
2 Show that \(\dfrac{4}{9} \div \dfrac{5}{6} = \dfrac{8}{15}\)
(2)
| Scheme | Marks |
|---|---|
| \(\frac{4}{9} \times \frac{6}{5}\) oe | M1 |
| \(\frac{24}{45}\) oe | A1 |
| (2 marks) |
Notes
M1: or \(\dfrac{0.8}{1.5}\)
A1: dep on M1. Accept \(\frac{8}{15}\) if clear cancelling seen
Alternative
| Scheme | Marks |
|---|---|
| \(\frac{8n}{18n} \div \frac{15n}{18n}\) for any integer \(n\) | M1 |
| \(\frac{8}{15}\) oe | A1 |
Notes
M1: \(\frac{8n}{18n} \div \frac{15n}{18n}\)
A1: dep on M1. Answer must come directly from their method eg \(\frac{16}{36} \div \frac{30}{36}\) must be followed by \(\frac{16}{30}\) for M1A1
