Answer:

Step-by-step explanation:

Alright, lets get started.

Suppose the first fraction is : [tex]\frac{a}{b}[/tex]

Suppose the second fraction is : [tex]\frac{c}{d}[/tex]

The sum of both fraction is given as : [tex]\frac{5}{6}[/tex]

[tex]\frac{a}{b}+\frac{c}{d}=\frac{5}{6}[/tex]    .......................equation (1)

The difference of both fraction is given as : [tex]\frac{1}{2}[/tex]

[tex]\frac{a}{b}-\frac{c}{d}=\frac{1}{2}[/tex]   .........................equation (2)

Adding equation (1) and equation (2)

[tex]\frac{c}{d} \ will \ be \ cancelled[/tex]

[tex]\frac{2a}{b}=\frac{5}{6}+\frac{1}{2}[/tex]

making common denominator

[tex]\frac{2a}{b}=\frac{5}{6}+ \frac{3}{6}[/tex]

[tex]\frac{2a}{b}=\frac{8}{6}[/tex]

Hence,

[tex]\frac{a}{b}=\frac{2}{3}[/tex]

Plugging the value of [tex]\frac{a}{b}[/tex] in equation (1)

[tex]\frac{2}{3}+\frac{c}{d}=\frac{5}{6}[/tex]

Subtracting [tex]\frac{2}{3}[/tex] in both sides

[tex]\frac{c}{d}=\frac{5}{6}-\frac{2}{3}[/tex]

[tex]\frac{c}{d}=\frac{1}{6}[/tex]

Hence both fractions are [tex]\frac{2}{3} \ and \ \frac{1}{6}[/tex]     ...................Answer
