Algebra 1

$3 \frac{1}{3} = \frac{10}{3}$ $35 = \frac{105}{3}$ $\sqrt \frac{4}{9} = \frac{2}{3}$ $\frac{10}{3} \div \frac{2}{3} = \frac{10}{3} \times \frac{3}{2} =\frac{30}{6} = 5$ $\frac{105}{3} \div \frac{2}{3} = \frac{105}{3} \times \frac{3}{2} =\frac{315}{6} = 52.5$ $52.5 * 5 = 262.5$ (rounded to 263 pavers)
