How do subtract whole numbers with fractions

1 answer:

6 0

You put the whole number over 1 then multiply so both fractions have the same denominator.
Example:
2- 1/2

2/1 -1/2

4/2 - 1/2 = 3/2 = 1 1/2

I’m not sure if this helped but I hope it did

Each interior angle of the regular n-gon has a measure of 140

xeze [42]

Sum of internal angles of any polygon is: (n-2)x180
So measure of an interior edge is ( ( n - 2 ) x 180 ) / n = 140
So 140n = 180n - 360
40n = 360
n = 9
So it's a nonagon.

Hope this helps :)
