Question

give me the answers of ticked question

Answer 1

let the numerator be x and denominator be y
then fraction will be x/y
according to the 1st condition
x+1/y=3/4
4x+4=3y
4x-3y=-4_1st equation

according to 2nd equation
x/y+2=1/2
2x=y+2
2x-y=2_2nd equation

2x=2+y
x=2+y/2_3rd equation
substitute in 1st equation

4(2+y/2)-3y=-4
8+4y-6y/2=-4
8-2y=-8
2y=16
y=8

3rd equation
x=2+8/2
x=10/2
x=5

hence,fraction=5/8
