Question 793663
<pre>
x:y:675=3:7:13

Rule:

if

a:b:c = d:e:f

then 

{{{a/d}} = {{{b/c}}} = {{{c/f}}}

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

Using the rule,

x:y:675 = 3:7:13

{{{x/3}} = {{{y/7}}} = {{{675/13}}}

Solve this to get x:

{{{x/3}}} = {{{675/13}}}

x = {{{2025/13}}}

Solve this to get y:

{{{y/7}}} = {{{675/13}}}

y = {{{4725/13}}}
