Question 473093
1)  what number must be added to each term of 5/8 to yield 3/4
Let x is a number
{{{(5+x)/(8+x)=3/4}}}
{{{4(5+x)=3(8+x)}}}
{{{20+4x=24+3x}}}
{{{4x-3x=24-20}}}
{{{x=4}}}
.
.
2) what number must be subtracted to each term of 9/17 to yield 1/3
Let x is a number
{{{(9-x)/(17-x)=1/3}}}
{{{3(9-x)=1(17-x)}}}
(((27-3x=17-x}}}
{{{-3x+x=17-27}}}
{{{-2x=-10}}}
{{{x=(-10)/(-2)}}}
{{{x=5}}}
