1.

find the fraction which is equal to 1/2 when both its numerator and denominator are increased by 2.it is equal to 3/4 when both are increased by 12.

Answer» LET the NUMERATOR be X and denomentar be y
(x+2)/(y+2)=1/2
2x+4=y+2
2x-y=-2
4x-2y=-4

when
(x+12)/(y+12)=3/4
4x+48=3y+36
4x-3y=-12

from both the EQ
y=8
x=3

so FRACTION is
3/8
