Ross and Lydia estimate the quotient for 387.5 divided by 73. Ross uses a whole number greater than the dividend. Which equation shows how Lydia uses compatible numbers to get a closer estimate?

Because as the dividend being assumed is greater than 387.5 as he is assuming a integer value greater than this. So the quotient will also be greater than 5.3. So there is only possibility B) Where 450> 387.5 and 6> 5.3
