[tex] \frac{1}{8} =0.125[/tex] (Half of [tex]\frac{1}{4}[/tex] which is 0.25
[tex]0.125 [/tex] x [tex]5[/tex] = 0.625
[tex] \frac{5}{8} =0.625[/tex]
-----------------------------------------------------------
An easier way to do it is to say [tex] \frac{5}{8}= \frac{4}{8} + \frac{1}{8} [/tex]
[tex] \frac{4}{8} =0.5[/tex] 1/8 = 0.125
0.500
+0.125
----------
0.625
