Answer 1

Answer:

see the explanation

Step-by-step explanation:

check the denominator for terminating or non terminating

if the denominator in the form of 2 power n and 5 power n

then it is terminating decimal if not non terminating decimal

Answer 2

TO FIND WHETHER A FRACTION IS IN TERMINATING OR NON TERMINATION REOCCURRING DECIMAL NUMNER FIRST WE HAVE SOME RULES

TERMINATING DECIMAL

: Terminating decimals are those numbers which come to an end after few repetitions after decimal point.

NON TERMINATING DECIMAL NUMNER :

= Non terminating decimals are those which keep on continuing after decimal point (i.e. they go on forever). They don’t come to end or if they do it is after a long interval.

Irrational Numbers:

We have different types of numbers in our number system such as whole numbers, real numbers, rational numbers, etc. Apart from these number systems we have Irrational Numbers. Irrational numbers are those which do not terminate and have no repeating pattern
