68 ÷ 170 = 0.4
0.4 * 100 = 40
68 of 170 = 40%
393 ÷ 60% = ?
60% ÷ 100 = 0.6
393 ÷ 0.6 = 655
393 is 60% of 655
The hundredths is the second place to the right, and following the rule of rounding, the number behind the 4 which is the hundredths place is greater than 5 which makes the 4 become a 5 so the answer is 12.15
