+R%5B1%5D+=+1%2F2+
+R%5B2%5D+=+1%2F8+
------------------
I could ask:
" What % of recipe 1 is recipe 2 ?"
+%28+1%2F8+%29+%2F+%28+1%2F2+%29+=+%28+2%2F1+%29%2A%28+1%2F8+%29+
+%28+1%2F8+%29+%2F+%28+1%2F2+%29+=+1%2F4+
+%281%2F4%29%2A100+=+25+
So, recipe 2 is 25% of recipe 1
---------------------------------------
I could also ask:
" How much more flour do I use in recipe 1 than recipe 2 ?"
+1%2F2+-+1%2F8+=+4%2F8+-+1%2F8+
+1%2F2+-+1%2F8+=+3%2F8+
so, I use 3/8 of a cup more in recipe 1
