how can you order three mixed numbers if each one has a different denominator such as 3 and 2/5 ,3 1/2 , 3 3/8

Sagot :

First, we need to convert the mixed number into a fraction

[tex]3\text{ }\frac{2}{5}=\frac{15}{5}+\frac{2}{5}=\frac{17}{5}[/tex][tex]3\frac{1}{2}=\frac{6}{2}+\frac{1}{2}=\frac{7}{2}[/tex][tex]3\text{ }\frac{3}{8}=\frac{24}{8}+\frac{3}{8}=\frac{27}{8}[/tex]

then we can convert them into a decimal number

[tex]\frac{17}{5}=3.4[/tex][tex]\frac{7}{2}=3.5[/tex][tex]\frac{27}{8}=3.37[/tex]

in a decimal number is easier to order the number for example the bigger to smaller

[tex]3\text{ }\frac{3}{8},\text{ 3}\frac{1}{2},3\frac{2}{5}[/tex]
