Answer	Mark	Comments
\(2w = \dfrac{4}{5} \times 15\) or \(2w = \dfrac{60}{5}\) or \(2w = 12\) or \(\dfrac{2w}{15} = \dfrac{12}{15}\) or \(\dfrac{w}{3} = \dfrac{2}{1}\) or \(\dfrac{w}{2} = \dfrac{3}{1}\) or \(\dfrac{w}{15} = \dfrac{4}{5} \div 2\) or \(\dfrac{w}{15} = \dfrac{2}{5}\) or \(2w \times 5 = 4 \times 15\) or \(10w = 60\) or \(\dfrac{4}{5} \div \dfrac{2}{15}\)	M1	oe in the form \(aw = n\) where \(a\) is an integer and \(n\) is an integer, fraction or decimal oe in the form \(\dfrac{bw}{x} = \dfrac{c}{x}\) where \(x\) is a common denominator oe calculation
