Question

A number is subtracted from the numerator of the fraction 12/13 and six times that number is added to the denominator . If the new fraction is 1/11, then find the number​

Answer 1

Answer:

let the no. be x

12-x/13+6x = 1/11

by cross multiplication

13+ 6x = 11 (12-x)

13 +6x = 132 -11x

taking x on one side,

6x + 11x = 132 - 13

17x =119

x = 119/17

x = 7
