Question

A fraction becomes equal to 4/5 if 1 is added to both numerator and denominator. If, however, 5 is subtracted from both numerator and denominator, the fraction becomes equal to 1/2. What is the fractions? @ answer down in photo 1 part 2part 3 part is only one answer

Answer 1

Answer:

i am sorry i donnot know

Answer 2

Answer:

7/9

Step-by-step explanation:

let x be numerator and y be denominator.

NOW, ATQ..

x+1/y+1 = 4/5

5(x+1) = 4(y+1)

5x+5 = 4y+4

5x-4y =-1 --(equation 1)

now,

x-5/y-5 = 1/2

2(x-5) = y-5

2x-10 = y-5

2x-y = 5 --(equation 2)

now, multiplying equation ii by 4 and subtracting equation I from ii.

8x-4y = 20

5x-4y = -1

- + +

------------------

3x = 21

x = 7

putting value in equation I we get

5×7-4y = -1

35-4y = -1

36 = 4y

9 = y

so the required fraction is 7/9
