The Half-way Decimal Game

The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

Chris, Fergus and Graeme play a game. Chris and Fergus each choose a decimal and Graeme tries to find the decimal that is half-way between Chris’ and Fergus’ decimals on the number line.

If Chris chooses 0.12 and Fergus chooses 0.012, what decimal should Graeme choose?
