Estimate the quotient by choosing a whole number close to the dividend that can be evenly divided by the divisor.
6.49/ 5= 1.298...????
14.78 / 5 = 2.956...????
If i understand the question correctly, the first answer would be 5 and the second is 15. The first answer rounds down to one so a close estimate would be 5/5 and the second rounds up to 3 so a close estimate would be 15/5.
