Drag each tile to the correct box. Order the expressions from least value to greatest value. ​

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}

2x² - 8x       5x - 20
2x(x - 4)      5(x - 4)
(2x + 5) (x - 4)
2x + 5 = 0      x - 4 = 0
2x = -5          x = 4
