thanks

54 x 0.85 = 45.9
Start with 1.00%:
If you're decreasing take that much off of the 1.00% (i.e. 15% off is 1.00 - 15 = 0.85)
If you're increasing then add that much on (so 15% increase is 1.15)
Then times that number by the number which is being increased/decreased - simple!

54 divided by 100 gives 1% which in this case is .54 to get 85% (100-15) you would do .54 x 85 which =45.9

15% of 54 =15 divided by 100 X 54=8.1
54-8.1=45.9
very interesting how everybody does it different ways!

15% is 15 ÷ 100. (15/100ths)
(15 ÷ 100) x 54 = 8.1
54 - 8.1 = 45.9
A quicker way is to say...100 - 15 = 85.
85/100 = 0.85
0.85 x 54 = 45.9

15% off for 54 would leave you with 45.90
i.e. => 54 - [54 x (15/100)]
=> 54 - [54 x 0.15]
=> 54 - [8.1]
=> 45.90
Got It !!!

Hello,
The answer to this Math question is the following:
15 divided by 100, and multiplied by 54 is equal to 8.1-54
OR: 15%X100X54= 8.1-54
Answer =45.9

The EASY way...
To get 10% move the point once to the left - 10% of 365 is 36.5 - to get 1% move it to the left again - 1% of 365 is 3.65
Now you have the tools to calculate the % of any given figure...
For example
54 minus 15% - well - 10% of 54 is 5.4 and 1% is .54
I hope I 've set you up for a lifetime of understanding how to work out percentages!
If you need further guidance - email me and I'll soon have you working out 1% of a fart!
(Joke, of course, all farts are 100%)

Hey there!
Use the formula for percent. P=S/T, where P is the percent, S is certain number of events in a set, and T is the total number of events in the set. Here's the answer.
P=S/T -->
15%=S/54 -->
0.15=S/54 -->
0.15(54)=S -->
S=8.1
Since the question said 15% off, we have to subtract S from T.
T-S -->
54-8.1 -->
45.9
So the answer is 45.9.
Hope it helps!

54 - 15% = 85% of 54
= 54 x 0.85 = 45.9

If it is 15% off, then you are keeping 85%, right? So you just multiply 54 by .85 to get your answer...
54 * .85 = 45.9
There is your answer :)
