What is 1/4 + 5/12?
What is 1/4 + 5/12?
Let's add
1
4
+
5
12
Step 1
Our denominators (bottom numbers) don't match, so we can't add yet.
Since 4 is evenly divided by 12, we can multiply just one term to get a common denominator.
Multiply 1 by 3, and get 3, then we multiply 4 by 3 and get 12.
The problem now has new fractions to add:
3
12
+
5
12
Step 2
Since our denominators match, we can add the numerators.
3 + 5 = 8
The sum we get is
8
12
Step 3
The last step is to reduce the fraction if we can.
To find out, we try dividing it by 2...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
8
12
÷ 2 =
4
6
Now, try the same number again.
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
4
6
÷ 2 =
2
3
Now, try the same number again.
Nope. Try the next prime number, 3...
No good. 3 is larger than 2. So we're done reducing.
Congratulations! Here's your final answer to 1/4 + 5/12

Answer:
Formula to the area of a parallelogram is A = base x height
A = 14.3 x 11.4
A = 163.02in^2
(you got it right!)
Answer:
at 8 pm the temperature will be -9 degrees. and at midnight the temperature will be negitive twenty one(-21) degrees
Step-by-step explanation:
the start time is 12 pm and finish is 12 am and every hour your going to subtract 3 from the given degree so 15-3= 12 , 12-3=9 ect.
Answer:
4.2
Step-by-step explanation:
use sin because you know the hypotenuse and you want to find the opposite side
sin(25)=y/10
10sin(25)=4.2
The only way that 2 lines don't intersect is when they are paralell
the only time 2 lines that are straight are paralell, is when the slopes are the same
find the slopes
slope=(y1-y2)/(x1-x2)
so the points of the line (0,-1) and (2,3) are
y1=-1
y2=3
x1=0
x2=2 so subsitute
(-1-3)/(0-2)=-4/-2=4/2=2
slope=2
the ohter one
points (-2,4) and (-3,3)
y1=4
y2=3
x1=-2
x2=-3
subsitute
(4-3)/(-2-(-3))=1/(-2+3)=1/1=1
slope=1
the slopes are different so they will intersect
