Answer 2

Answer:

(a) 47/18

(b) 37/2

Step-by-step explanation:

(a)

$\frac{2}{3} ( \frac{3}{4} + \frac{2}{3} + \frac{5}{2} )$

$= \frac{2}{3} ( \frac{9 + 8 + 30}{12} )$

$= \frac{2}{3} \times \frac{47}{12}$

$= \frac{47}{18}$

(b)

$( 6\frac{2}{5} \times \frac{25}{8} ) - ( \frac{4}{3} \times 1\frac{1}{8} )$

$= ( \frac{32}{5} \times \frac{25}{8} ) - ( \frac{4}{3} \times \frac{9}{8} )$

$= ( 4 \times 5 )- ( \frac{3}{2} ) = 20 - \frac{3}{2}$

$= \frac{40 - 3}{2} = \frac{37}{2}$

Hope It Helps :)
