Divide 26.80 by 4 and then multiply that by 13. I got 87.10 (What a loser).

Let's call the paycheck "P," and the donation "D."
4/13 of P = D
(4/13) x P = D
You know D (26.80), so solve for P:
(4/13) x P = (26.80)
P = 26.80 x (13/4)
P = 87.10
If P = 87.10, then the paycheck (P) is $87.10.

(4/13) of the paycheck equals $26.80
In algebra, that means:
(4/13) * x = 26.80
(13/4) * (4/13) * x = 26.80 * (13/4)
1 * x = 87.10
x = $87.10

Here's an easy way (there are others, of course)
If $26.80 is 4/13ths of his pay, then you can divide by $26.80 by 4 to get 1/13 of his pay. -- 26.80 / 4 equals $6.70--. Then you can add 6.70 13 times or just multiply 6.70 x 13. (You can do this...I believe in you...just do the steps and you'l have your answer!)
Sometimes it helps to break it down to the smallest and easiest possible way to help you understand the functions. One very good site is FunBrain.com. It makes learning easy buy using games and puzzles and trivia. It's fun! Let me know if you need more links for help.

4/13 of X = 26.80
"of" means times, so
4/13 times X = 26.80
divide both sides by 4/13, we have
X = 26.80 / 4/13
X = 26.80 * 13 / 4
X = $87.10

Let x be his wage, and d what he donates. Then you have
d=(4/13)*x
To get x you divide both sides 4/13 which gives you:
x=(13/4)*d
Insert 26.80 into d. You get x=87.10.

26.80 / 4 = how much 1/13 is, then times that number by 13 for his total paycheck...
She was asking for help because he didn't know... wow ppl.... just answer the Q.

Let P be his paycheck
P x 4/13 = 26.80
(P x 4)/13 = 26.80
Multiply both sides by 13 to get:
P x 4 = 348.40
Divide both sides by 4 to get:
P = 87.10
So his paycheck is $87.10

4/13 = 0.307692308
Decimal Equivalent
26.80/0.307692308 = 87.10
26.800 divided by 0.307692308 = 87.10

2nd Method
Proportional problem
x = amount of thepaycheck
4/13 = 26.80/x
384.4 = 4x
Cross multiply the means by the extrems
384.4/4 = 4x/4
Dividing both sides by 4
87.10 = x
The amount of the paycheck is $ 87.10
The answer is $ 87.10
