Step-by-step explanation:
let the original ratio be x.
Therefore, the ratio is 8x and 7x.
two is subtracted from both numbers,the ratio changes to 7:6.
therefore, 8x-2/7x-2=7/6
by cross multiplication,
6(8x-2)+7(7x-2) = x
48x-2+49x-2=x
46x+47x=x
83x=x
: . x=83
Therefore,substitute the value of x.
: . 8x=8(83)=664 degree
7x=7(83)=581 degree
