Answer:

$\frac{5}{-1.6}$

Step-by-step explanation:

We will solve the given expressions and find the answer in decimals.

1). $5\frac{6}{15}+(-2\frac{4}{5})$ = $5\frac{2}{5}-2\frac{4}{5}$

= 5.4 - 2.8

= 2.6

2). $-3\frac{3}{10}-(-\frac{7}{20})=-3\frac{3}{10}+\frac{7}{20}$

= -3.3 + 0.35

= -2.95

3). $\frac{5}{-1.6}=-\frac{5}{1.6}$

= -3.125

4). (-4.5) × (-2.3) = 10.35

Solution of the expressions in the increasing order will be,

-3.125 < -2.95 < 2.6 < 10.35

$\frac{5}{-1.6}$

2x(x - 4) 5(x - 4)
(2x + 5) (x - 4)
2x + 5 = 0 x - 4 = 0
2x = -5 x = 4
x = -5/2
