The following steps for successive magnification to visualise 2.665 are:

(a) We observe that 2.665 is located somewhere between 2 and 3 on the number line. So,

let us look at the portion of the number line between 2 and 3.

(b) We divide this portion into 10 equal parts and mark each point of division. The first

mark to the right of 2 will represent 2.1, the next 2.2 and soon. Again we observe that

2.665 lies between 2.6 and 2.7.

(c) We mark these points A_{1 }and A_{2} respectively. The first mark on the right side of A_{1} , will

represent 2.61, the number 2.62, and soon. We observe 2.665 lies between 2.66 and 2.67.

(d) Let us mark 2.66 as B_{1 }and 2.67 as B_{2} . Again divide the B_{1}B_{2} into ten equal parts. The

first mark on the right side of B_{1}will represent 2.661. Then next 2.662, and so on.

Clearly, fifth point will represent 2.665.
