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)
