Divide 14 by 25. Then you should get a decimal number. take the decimal number and multiply by 100 and done!
Answer:
80/111
Step-by-step explanation:
For starters, since it is 3 digits inclusive of 0, from 0 - 9, then there are 1000 possible total plate combination from 000 - 999.
If no number is expected to be repeated in the combination, then there exists 10 numbers(say 0-9) for the first digit, 9 numbers(say 1-9) for the second digit and 8 numbers(1-8) for the third digit.
This means that there will be 10 * 9 * 8 total possible outcomes. Considering that the possible combinations is 999, then the probability is
10 * 9 * 8 = 720/999
And that is simplified to 80/111
The change from 10 to 11 or from 100 to 101 is 1 in each case.
In the first case, the percentage of change is 1/10 = 10%.
In the second case, the percentage of change is 1/100 = 1%.
The percentages of change are different because the bases from which the change is measure are different.
7x-3=7x+5
+3 +3
7x=7x+8
-7x-7x
x=8
