Answer»

Given:-

⠀⠀⠀◍ The NUMERATOR of a fraction is 8 ⠀⠀⠀⠀less than its denominator.

⠀⠀⠀◍ If 12 is added to both numerator ⠀⠀⠀⠀and denominator, the fraction ⠀⠀⠀⠀becomes 11/19.

To FIND:-

⠀⠀⠀◍ The fraction.

Let:-

⠀⠀⠀◍ Fraction be

⠀⠀⠀◍ \sf\dfrac{x}{y}

According to the question

⠀⠀⠀✯ x = y - 8⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀Eq......... i

⠀⠀⠀✯ \sf\dfrac{x + 12}{y + 12} = \dfrac{11}{19}

Solution:-

⠀⠀⠀✯ 19 (x + 12) = 11 (y + 12)

⠀⠀⠀✯ 19x + 228 = 11 y + 132

⠀⠀⠀✯ 19x - 11y = 132 - 228

⠀⠀⠀✯ 19x - 11y = -96

⠀⠀⠀✯ 19 (y - 8) - 11y = -96

⠀⠀⠀✯ 19y - 152 - 11y = -96

⠀⠀⠀✯ 8Y = -96 + 152

⠀⠀⠀✯ y = \sf\dfrac{56}{8}

⠀⠀⠀✯ y = 7

◍ Putting the value of y in Eq...... i

⠀⠀⠀✯ x = y - 8

⠀⠀⠀✯ x = 7 - 8

⠀⠀⠀✯ x = -1

Answer:-

⠀⠀⠀★ The fraction = \sf\dfrac{x}{y}

⠀⠀⠀★ The fraction = \sf\dfrac{-1}{7}
