Question

2 state whether the following are
terminating decimal-terminating
reccoring
decimals without actual
division
(i) 17
128
(81) 24
400
(ii) 24
980​

Answer 1

Answer:

factors of denominator

128 =2"2"2"2"2"2"2

therefore terminating

400=2*2*2*2*5*5

terminating

980=2*5*7*7*2

since the denominator has a 7*7 and numerator doesn't have factors of 49 therefor nonterminating
