Here are the numbers
4.3 , 5.5 , 6[tex] \frac{1}{6} [/tex] , [tex] \frac{15}{4} [/tex] , 4[tex] \frac{3}{8} [/tex]
I'm going to change them into fractions
In the fractions, divide the numerator by the denominator
[tex] 6\frac{1}{6} [/tex]⇔6.1666---
[tex] \frac{15}{4} [/tex]⇔3.75
[tex]4 \frac{3}{8} [/tex]⇔4.375
Now to arrange them from least to the greatest
[tex] \frac{15}{4} [/tex] , 4.3 , [tex]4 \frac{3}{8} [/tex] , 5.5 , [tex] 6\frac{1}{6} [/tex]
