To calculate 6% of a number, you multiply that number by 0.06. To calculate 75% of a number, you multiply that number by 0.75. If you want to know what 6% of a number is when it is deducted from 75% of that number, you would need to first calculate 6% of the number and then subtract it from 75% of the number. Here is an example:

Suppose you have a number that is 100. 6% of 100 is 0.06 * 100 = 6. 75% of 100 is 0.75 * 100 = 75. If you subtract 6 from 75, you get 69. Therefore, 6% deducted from 75% of 100 is 69.

The simple answer is 69.
