Find three rational numbers between each pair of fractions
A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero, e.g 2/3, 7/2 etc
1) 1/3 and 3/4
Three rational numbers between them are
[tex]\frac{5}{12},\frac{1}{2},\frac{3}{5}[/tex]2) 1/5 and 2/3
Three rational numbers between them are
[tex]\frac{7}{15},\frac{8}{15},\frac{9}{15}[/tex]3) 3/8 and 5/6
Three rational numbers between them are
[tex]\frac{11}{24},\frac{1}{2},\frac{4}{6}[/tex]4) 1/4 and 4/5
Three rational numbers between them are
[tex][/tex]3) 1/6 and 2/5
Three rational numbers between them are
[tex]\frac{7}{30},\frac{8}{30},\frac{9}{30}[/tex]4)
