Decreasing value from 60 to 39 is 60-39=21
If the value of 60 is 21, what is the value of 100?
60 21
100 ?
_________
?=21*100/60
?=35
Answer: 35%
The last one is the correct answer
The answer for the binary number 10101 is 21
So to figure out 10% of this would be to remove the 0. that would be six. since 30÷10 is 3, we have to do 6×3. that would be 18, so 30% of 60 is 18
