20 more women needs to join for the ratio to be 5:4.
7:2 = 45 people
45 decide 9=5people
7•5=35people (men)
7•2=10people (women)
35(men)
10+20=30(women)
35:30 = 5:4
use the quadratic formula, we must.
-13 +/- √(169 +48) / 2
-13 +/- √217 / 2
-13 +/- 14.73 / 2
(-13 + 14.73) / 2 = 0.865
(-13 - 14.73) / 2 = -13.865
the solutions, we have found.
helped, i hope i have.
