Question

Benni wants to divide 48.6 by 0.7. In order to estimate the quotient, which is the best expression to use?

Answer 1

Answer: The answer is D

Step-by-step explanation:The reason for this is because 48.6 is closer to 50 and also when its rounded its about 50 not 40.In addition,0.7 is turned into 1 because its higher .5 which means it would be consider 1.For example, if the number is 16.6 it will be rounded up to 17.

Answer 2

Answer:

Option D - 50÷1

Step-by-step explanation:

Given : Benni wants to divide 48.6 by 0.7.

To find : In order to estimate the quotient, which is the best expression to use?

Solution :

In order to estimate i.e. an approximate calculation we round the numbers,

48.6 as tenth place is > 5 then it round completely

$48.6\approx 50$

0.7 as tenth place is > 5 then it round completely

$0.7\approx 1$

So the estimated expression is given by,

$48.6\div 0.7=50\div 1$

Therefore, option D is correct.
