# Thread: [Easy +rep] 7th Grade - Pre-Algebra [Updated Every time I feel lazy]

1. ## [Easy +rep] 7th Grade - Pre-Algebra [Updated Every time I feel lazy]

Though Math is my best grade (A+) it feels unnecessary to do the homework. This thread will be updated every time i feel lazy.
Reps will be given to those who give the correct answers and show their work in format.

Format Example
(10 x 5)5 x 9
= (50 x 5) x 9
= 250 x 9
= 2250

Problems of the Day ~
None. Reps awarded for the day. Stay tuned.

Thanks

2. 10)
a/100 x 80 = 10
8a=10x10
8a=100
a=12.5%

3. x/100=80/10
80x=1000
Divide Both Sides by 80
x= 12.5
So 10 is 12.5 Percent of 80

4. edit: Nevermind I don't know what I was saying xD

5. 10) 10/80= 0.125
0.125*100= 12.5%

14) 45/100=9.9

18) 16/80=0.2
0.2*100=20%

22) 6/24=0.25
0.25*100-25

I can't wait til the next time this is updated.
I love(d) Pre-Algebra, Algebra I, Algebra II, and College Algebra.
Now I've taken every Algebra course I can until I actually go off to college. D:
ENJOY IT WHILE YOU CAN, IT MAY BE MATH, BUT IT'S THE BEST KIND OF MATH.
GEOMETRY AND TRIG ARE THE DEVIL.
