Answer:
Step-by-step explanation:
Area = L * W
L = 1/2
Area = 5/16
5/16 = 1/2 * w You could do this using decimals
5/16 = 0.3125
1/2 = 0.5
0.3125 = 0.5 * w
w = 0.3125/0.5
w = 0.625
w = 5/8
The other way is done by fractions

There are a couple of notes
- First, you invert and multiply the denominator (the bottom fraction). It becomes 2/1
- Second the 2 and 16 cancel 5/16 becomes 5/8
You see, I'm not a fraction pleb. I do it decimal way.
Ok, fine I will.
7 1/8 = 57/8
57/8 x 2/1 = 114/8
This can be simplified to 57/4, 14 1/4, or 14.25
It would be rounded to 300,000
251,000
For this check the hundreds, tens, ones. If it's 500 of more round it up
