Answer::
[tex]\frac{9}{12},\frac{1}{2},and\text{ }\frac{3}{4}[/tex]Explanation:
Given the fractions:
[tex]\frac{9}{12},\frac{1}{2},\frac{3}{8},\frac{6}{10},\frac{8}{15},\frac{3}{4}[/tex]Reduce each of the fractions to their lowest form.
[tex]\frac{3}{4},\frac{1}{2},\frac{3}{8},\frac{3}{5},\frac{8}{15},\frac{3}{4}[/tex]On observation:
[tex]\frac{3}{4}+\frac{1}{2}+\frac{3}{4}=\frac{3+2+3}{4}=\frac{8}{4}=2[/tex]Therefore, the three fractions whose sum is a whole number are:
[tex]\frac{9}{12},\frac{1}{2},and\text{ }\frac{3}{4}[/tex]
