No Division ! q के Factors ही बता देंगे – Terminating or Not ? | Class 9/10 CBSE

No Division ! q के Factors ही बता देंगे – Terminating or Not ? | Class 9/10 CBSE In this video, Gaurav Arora sir explains: • Rational numbers are of two types: – Terminating decimal expansion: remainder becomes zero – Non-terminating but repeating: remainder never becomes zero, but a digit or a block of digits keeps repeating • One question is solved where four rational numbers are given • From these, we have to identify which number is non-terminating but repeating • Without dividing, this trick is explained by Gaurav Arora sir • You only need to factorize q • If the factors of q are in the form of 2^m × 5^n: – The number will be a terminating decimal expansion – The remainder becomes zero in the beginning or after certain steps • If the factors of q (denominator) are other than 2^m × 5^n: – The rational number will be non-terminating but repeating #sirgauravarora #gauravarorasir #sirgauravaroralive #mathskabadshaah #cbse #class9 #class10
