can i half my healthy extras??

I have a question......
Can I half my healthy extras? As in have milk in my mornin cuppa, then have half an allowance of cheese??
Also my mum is makin a curry using a can of homepride curry sauce but my food directory only gives the value as 10.5 syns for the whole can! How do I work out how many syns my portion would be???? HELP!!

Thats fab, thanks hun. Will enjoy my cuppa guilt free now lol.
I thought tht was how to work it out, just wanted to be certain x
