4 over 9 plus 2 over5?
Make lower part the same i.e. 9 x 5 = 45 So 4 / 9 = 20 / 45 and 2 / 5 = 18 / 45 Then 20 + 18 = 38 Answer: 38 / 45
What two numbers multiply to get 315 and add to get 52?
1) x*y=315 2) x+y=52 from 2, x=52-y, put into 1, y*(52-y) = 315 or y^2-52*y+315=0 delta= (-52)^2-4*1*315=1444 = 38^2 y = (52-38)/2 = 7 or y = (52+38)/2 = 45 then x = 45 or x = 45
