Question

Va rog mult sa ma ajutati la punctul b!!

Answer 1

$a)(3 - \frac{1}{3} ) \times ( \frac{9}{8} ) {}^{2}$

$\frac{8}{3} \times \frac{81}{64}$

$\frac{27}{8}$

$b) \frac{3}{4} \div ( \frac{3}{4} - \frac{1}{2}) - \frac{4}{9}$

$\frac{3}{4} \div \frac{1}{4} - \frac{4}{9}$

$\frac{3}{4} \times 4 - \frac{4}{9}$

$3 - \frac{4}{9}$

$\frac{23}{9}$
