Answer: 4 9/10
Step-by-step explanation: You need to subtract 12 2/5 and 7 1/2.
The two fractions have different denominators. Multiply to find a common denominator
2/5 x 2/2 = 4/10
1/2 x 5/5 = 5/10
Now you have 12 4/10 minus 7 5/10. But you cannot subtract 4/10 and 5/10 equally.
Subtract 12 - 1 and add 1 to 4/10.
12 - 1 = 11
10/10 (10/10 is 1) + 4/10 = 14/10
Now you have 11 14/10 minus 7 5/10. Subtract.
11 - 7 = 4
14/10 - 5/10 = 9/10
That makes 4 9/10.

<h3>The changes to a polygon</h3>
1. If the number of sides of the polygon should increase then the measure of the interior angle would increase by 180.
2. A regular polygon has the sum of its external angles as 360. This is solved as 360/n = 0
Hence the value of the exterior would move towards 0 as its sides increases.
4. As the total sum of the of the polygon changes, it would tend towards infinity.
5. The total sum of the exterior angles as the number of sides changes would tends towards 360 degrees.
