(a) Write these numbers in order of size.
Start with the smallest number.

\(\dfrac{7}{9} \qquad \dfrac{8}{11} \qquad 0.79 \qquad 84\% \qquad \dfrac{4}{5}\)

(3)

(b) Find the value of \(3^5\) (1)

(d) Find the value of \(\sqrt[3]{17.576}\) (1)

Eg 0.72/3..., 0.77..., 0.79, 0.8, 0.84 \(\dfrac{8}{11} = 0.7272\ldots\) \(\dfrac{7}{9} = 0.777\ldots\) \(\dfrac{4}{5} = 0.8\) Answer: \(\dfrac{8}{11}, \dfrac{7}{9}, 0.79, \dfrac{4}{5}, 84\%\)	B3

Notes

B3: Accept correct decimal/percentage equivalents in ascending order

If not B3 then award B2 for:

• 4 numbers in the correct order or

• \(\dfrac{8}{11}\) and \(\dfrac{7}{9}\) and \(\dfrac{4}{5}\) correctly converted to decimals or %’s (at least 2 SF rounded or truncated for \(\dfrac{8}{11}\) & \(\dfrac{7}{9}\)) or

• all five numbers in correct descending order.

If not B2 then B1 for

• 3 numbers in the correct order provided it is not the original list

• 2 fractions from \(\dfrac{8}{11}, \dfrac{7}{9}, \dfrac{4}{5}\) correctly converted to decimals or %’s (at least 2 SF rounded or truncated)
