Question

(3 - 1/3) ×(9/8)la2 + 3/4 : (3/4 - 1/2) - (3/2)la2 =
repede plz

Answer 1

$(3 - \frac{1}{3} ) \times ( { \frac{9}{8} )}^{2} + \frac{3}{4} \div ( \frac{3}{4} - \frac{1}{2} ) - ( { \frac{3}{2}) }^{2}$

$= ( \frac{9}{3} - \frac{1}{3} ) \times \frac{ {9}^{2} }{ {8}^{2} } + \frac{3}{4} \div ( \frac{3}{4} - \frac{2}{4} ) - \frac{ {3}^{2} }{ {2}^{2} }$

$= \frac{9 - 1}{3} \times \frac{81}{64} + \frac{3}{4} \div \frac{3 - 2}{4} - \frac{9}{4}$

$= \frac{8}{3} \times \frac{81}{64} + \frac{3}{4} \div \frac{1}{4} - \frac{9}{4}$

$= 1 \times \frac{27}{8} + \frac{3}{4} \times 4 - \frac{9}{4}$

$= \frac{27}{8} + \frac{12}{4} - \frac{9}{4}$

$= \frac{27}{8} + \frac{24}{8} - \frac{18}{8}$

$= \frac{27 + 24 - 18}{8}$

$= \frac{69}{8}$
