Question

Arrange from the least to the greatest: $0.55,-\frac{7}{8},-0.8,\frac{5}{8},3$

Answer 1

Arrange the sequence of numbers from least to the greatest
Given,
The sequence of numbers are$0.55,-\frac{7}{8},-0.8,\frac{5}{8},3$
Simplify the above fractions in to like fraction,
$\begin{array}{rcl}0.55& =& \frac{550}{1000}\\ \frac{-7}{8}& =& -0.875=\frac{-0.875}{1000}\\ -0.8& =& \frac{-0.800}{1000}\\ \frac{5}{8}& =& 0.625=\frac{625}{1000}\\ 3& =& \frac{3000}{1000}\end{array}$
Now, follow the ascending order, jea going from least to greatest:
$$\begin{gathered} \frac{-0.875}{1000}<\frac{-0.800}{1000}<\frac{550}{1000}<\frac{625}{1000}<\frac{3000}{1000} \\ \therefore -0.875<-0.8<0.55<0.625<3 \end{gathered}$$
Hence, the numbers arranged from the least to the greatest is $-\frac{7}{8}<-0.8<0.55<\frac{5}{8}<3$.
