Question 1020169
{{{J=2A}}} Joe has twice as much as Ada
.
.

{{{A=(1/2)O}}} Ada has half as much as Oli
So,
{{{O=2A}}} Oli also has twice as much as Ada.
All together,
{{{J+A+O=5.25}}}
You can substitute,
{{{2A+A+2A=5.25}}}
{{{5A=5.25}}}
{{{A=5.25/5}}}
Now solve for A.
Then go back and find J and O.
