Let +x+ = amount Jeremy has
+x+%2B+10+ = amount Carlos has
+x+-+5+ = amount Michelle has
------------------------------
+x+%2B+x+%2B+10+%2B+x+-+5+=+80+
+3x+%2B+5+=+80+
+3x+=+75+
+x+=+25+
------------------
Michelle has +x+-+5+
+x+-+5+=+25+-+5+
+x+-+5+=+20+
----------------
+20+%2F+100+=+1%2F5+
Michelle has 1/5 of 100
