What is a fraction?

A fraction is the ratio of two integers.

it is usually two integers written above and below and dividing line.

These integers are called numerators and denominators.

Analysis:

Let the number be x

1 1/2 =5/2,  1 5/6 = 11/6   1 1/5 = 6/5

(5/2x / 6/5) - 7/18 = 11/6

(5/2x × 5/6) - 7/18 = 11/6

25x/12 - 7/18 = 11/6

taking LCM of 12 and 18

[tex]\frac{75x-14}{36}[/tex] = 11/6

6(75x - 14) = 11 x 36

75x - 14 = 6 x 11

75x = 66 + 14

75x = 80

x 80/75 = 16/15

In conclusion, the number is 16/15
