\( 6 \times 2 \frac{9}{10} \) Write your answer as a mixed number in simplest form.

(ii) \( \begin{array}{r}5.129 \times(-0.15) \\ .23 \\ 5.129 \times 6\end{array} \)

2 Round R269,90 to the nearest R100 rand.

Simplify \( 6+3 \times 5 \) \( 20-7 \times 2 \) \( 4+5 \times 4 \)

stion 1 ie has \( 35 \frac{3}{4} \) yards of red ribbon and \( 30 \frac{1}{3} \) yards of green ribbon. She cuts the red ribbon into strips tha yards long and the green ribbon into strips that are each \( 2 \frac{1}{6} \) yards long. How many more green strips ps does she have?

If \( a=5.6(1 \mathrm{dp}), b=24.1(1 \mathrm{dp}), c=145 \) (3sf) \( \mathrm{d}=0.34(2 \mathrm{dp}) \) Calculate the upper \& lower bounds to \( 3 s f \). \( {c d^{3}}^{3} \)
