The quotient is 45 1/4 what is the divisor

vredina [299]

1. Well if the quotient is 45 ¼, the divisor will depends on the dividend.
Since the dividend is not given, there it would be hard for us to tell what is the divisor.
Because we only have the quotient, there are a lot of answers then if the dividend is not given.
it can be that the divisor is 2 and the dividend is 90 ½ to be able to get 45 ¼ as an answer.
it’s hard to tell without identifying the dividend.
