+Stephen Barker - Glad to help. You should get marks but they can be quite strict - here's a video on significant figures ruclips.net/video/oDkWiC2KrvY/видео.html and one on decimal places ruclips.net/video/7hi20-UPRJQ/видео.html. All best S :-)
+Stephen Barker - Hi - "estimate" is really code for "calculate with one sig fig" so: (60.2 x 0.799) / 223 would be (60 x 0.8) / 200 48 / 200 0.24 Here's a playlist with a couple of examples: ruclips.net/p/PLPglScc3TJ-O3h81mzkzTLFWLjzSNEJP_ Best S

Simon Deacon so would i always use sig figures the question is work out an estimate for 60.2x0.799/223 answers are in the range of 0.24 and 0.3

(60 x 0.8) / 200
