Answer 1

explaination

we have to find the LCM of demominator if the factors are other than 2or 5 then the number is non terminating decimal

if the LCM of demominators factor is 2 or 5 then the is terminating decimal

so I hope That you have understood the terminating or non terminating decimal

so this is the explanation

answer is

1)7/80

LCM 80= 2,2,2,5

so the factors of 80 is 2or 5 only

thus, the 7/80 is the terminating decimal

now, you solve the other question if you can't then please follow me I will tell you the answers

I hope this helps to you

Answer 2
