Please answer fast, please

Answer 1

See terminating decimals are those in which the number 2 and 5 are seen in the denominator after factorising

Example : 11/20
Factorise 20 you will get 2*5*2
That can be written as 2^2 *5

You can see only 2 and 5 in the denominator hence the number 11/20 is a terminating number

Similarly you can solve all the other parts

Remember all rational numbers are terminating
