You can put this solution on YOUR website!
If you label their ages +a+, +b+, and +c+
+a+-+b+=+1+%2B+9%2F12+
+c+-+b+=+2+%2B+8%2F12+
—————————————-
Find +a+-+c+
+a+=+b+%2B+1+%2B+9%2F12+
+c+=+b+%2B+2+%2B+8%5C12+
——————————————
+a+-+c+=+b+%2B+1+%2B+9%2F12+-+b+-+2+-+8%2F12+
+a+-+c+=+-1+%2B+1%2F12+
+a+-+c+=+-11%2F12+
Abi is 11 months younger than Cam
———————————————————-
Note that if you multiply both sides by +-1+
+-a+%2B+c+=+11%2F12+
+c+-+a+=+11%2F12+
This shows that Cam is older and Abi is younger
