Answer 1

Answer:

Question 1. Write the following in decimal form and say what kind of decimal expansion each has

Solution: (i)36/100 = 0.36 and it is terminating.

(ii) by long division method we get

And

(iii) 1/11 = 0.090909090……….

So it is a non terminating number

4.125 is a terminating number

(iv)

We are getting 3/13 = 0.230769230769230769…..

There is repetition of 230769 so it is a non terminating number

(v)

2/11 = 0.18181818 ……..

There is repartition of 18 so it is not terminating number

(vi)

329/400 = 0.8225
