If I cut 2/3 of a pie and put the big piece on my plate. Then eat 1/4 of the piece. What fraction of the original pie did I eat.
2 answers:
2/3 = 8/12 (GCD of 3 and 4 is 12. 3 * 4 = 12, 2 * 4 = 8)
1/4 = 3/12 (4 * 3 = 12, 1 * 3 = 3)
8/12 - 3/12 = 5/12
You ate 5/12 of the pie
I'm not sure if this really helps anyone that reads it, but that's how I was taught. You can correct me if I'm wrong.
P.S. I know I'm late for it
If you took

of a pie then only ate

of that slice, you ate

of

.

Simplify.

So, you ate 1/6 of the pie.

Answer:
The answer to your question is: both lines are the same.
Step-by-step explanation:
3x + 3y = 10
-9x -9y = -30
Elimination method
9x + 9x = 30
-9x - 9y = -30
0 0 0
In math, "of" almost always means "times".
So your question is: 3/7 times (the number) = 9
Multiply each side of that equation by 7 : 3 times (the number) = 63
Divide each side by 3 : <em> The number = 21</em>
Answer:
1386 square units
Step-by-step explanation:
Area of a cirlce = Pi x r^2 [ Pi is 22/7 as stated in question]
22/7 x 21^2 = 1386 sq. units
Well it would be (x+3)(x+3)
using the FOIL method you end up with:
x^2 + 6x + 9
