Estimate the result by rounding the numbers to the second decimal before performing the operation. Then also round your answer to the second decimal.
3.15÷0.0318
8123÷0.211

1) 105.00

ii) 38,680. 95

Step-by-step explanation:

1) 3.15÷0.0318

Now, we have to round the number to two decimal places

3.14 = already rounded to two decimal places

0.0318 = have four decimals

Now, the rule of rounding the decimals says that if the number next to rounding digit is less than 5 then drop all the numbers right to the rounding digit. In contrast, if the number is 5 or grater than that, add one to rounding digit.

So,

0.0318 = 0.03 (as 1 is less than 5)

Now by performing the operation

3.15÷0.03

=> 105

or 105.00 (rounding to two decimal places)

2) 8123÷0.211

8123 = already rounded to two decimal places

0.211 = have three decimals

Converting it to two decimals,

0.211 = 0.21 (as 1 is less than 5)

Now by performing the operation

8123÷0.21

=> 38,680. 95238

=> 38,680. 95 (as 2 is less than 5)
