1/2 is equivalent to 2/4 because,
2(1/2) = 2/4
So as you can see if you multiply the numerator(top) and the denominator(bottom) by the same number, you get an equivalent fraction! In my example you can see that I multiplied both by 2.
80% is the answer to ur question
Central angle is 130
Semi circle is BED and BCD
Major arc is CEB
Measure BAC is 130
BEC is 230
160 inches long
40 + 40 gets you 80 add that with another 80 since the other two sides will add up to that then you’ll have yourself 160
