Help quick please. Order the numbers from least to greatest.
Anastasy [175]

Answer:

-2\frac{1}{4}

Step-by-step explanation:

Mod of any number represents the absolute value of the number.

Therefore, |-2\frac{1}{4}|=2\frac{1}{4} = 2.25

-2\frac{1}{4}=-2.25

|1\frac{1}{4}|=1.25

\frac{3}{4}=0.75

|-1\frac{3}{4}|=1\frac{3}{4}=1.75

-1\frac{1}{4}=-1.25

Now we can arrange these numbers in ascending order.

-2.25 < -1.25 < 0.75 < 1.25 < 1.75 < 2.25

Therefore, -2\frac{1}{4}
