On the line below, mark the point that is 6.7 centimetres from A.

We need to use a ruler to help us measure accurately. The markings on this ruler are in millimetres. This is why the numbers are marked in multiples of 10: 10, 20, 30, and so on. We know that one centimetre is equal to 10 millimetres. And we need to mark the point that is 6.7 centimetres from point A.

So 6.7 centimetres is the same as 67 millimetres. This point here shows 60 millimetres or six centimetres. And this point shows seven centimetres or 70 millimetres. So we know that our point will be somewhere between 60 and 70 millimetres. The line halfway between 60 and 70 millimetres is 65 millimetres. And each of the smaller divisions represent one millimetre. So we need to count forward two more millimetres.

So this point right here shows 67 millimetres or 6.7 centimetres. The question asks us to mark this point. We used a ruler to help us find 6.7 centimetres from point A.
