Were doing calculations in lessons but only thing i cant work out is when they use % how do you work out a dose of a drug if they have e.g. A 2.5% solution?

If anyone tries to teach me a different formula I just get confused. :P</p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/147631?ContentTypeID=1Thu, 21 Nov 2013 08:54:04 GMT1a0763ec-3885-442c-853e-6cef656dfec5:b3bc8702-029f-458f-926c-a4d3a99de038Jack Player<p>thanks, you make it sound so simple.
