Steps To Solve:
~Find common denominators
6/7 = 54/63
2/9 = 14/63
~Turn into improper fractions
1 54/63 = 117/63
4 14/63 = 266/63
~Subtract.
266/63 - 117/63 = 149/63
~Turn into mixed number
149/63 = 2 23/63
~Round
2 23/63 ≈ 2 1/2
Ответ:
10,000 voters
Step-by-step explanation:
male voters
let the x represent the total number of voters
for male voters
130/360 *x = 0.36x
for female voters
angle for female voters
360 - 130 = 230°
230/360 *x = 0.64x
but there were 2800 more female voters than males
this gives;
2800 + 0.36x
equating the two values of female voters
0.64x = 2800 + 0.36x
collect like terms
0.64x - 0.36x = 2800
028x = 2800
x = 10,000
Therefore, there were 10,000 voters
