$( \frac{9}{32} \times \frac{5}{6} )\times \frac{8}{15} \\$
Let's do the bracket part first,
and solve further as shown,
$( \frac{3}{32} \times \frac{5}{2}) \times \frac{8}{15} \\ = \frac{15}{64} \times \frac{8}{15} \\ = \frac{8}{64} \\ = \frac{1}{8}$

HELP WITH 10 QUESTIONS?!?! HERE IS THE FIRST 1.

madreJ [45]

5x - 5y = 10
x - y = 2 . . . (1)
3x - 2y = 2 . . . (2)

(1) x 3 => 3x - 3y = 6 . . . (3)
(2) - (3) => y = -4

From (1), x - (-4) = 2
x = 2 - 4 = -2

Solution is (-2, -4)
