= 15/25
we divide the Nm Dm with number 5. But why only with 5 why we can't take any other number

explain me step by step​

Answer 1

Answer:

because when we have to divide any rational number we have to divide numerator and denominator with same number. so here, 5 is the only number which divides both numerator and denominator and also there is no another number which Divides 15 and 25 . so, we can't take any other number.
