the third part is 220
let the 3 part be x,y and z
so 4x=5y
y=4/5x
4x=7z
z=4/7x
x+y+z=913
x+4/5x+4/7x=913
by solving the equation ull get
x= 385
so by putting in it equation
z=4/7*385
z=220
let the 3 part be x,y and z
so 4x=5y
y=4/5x
4x=7z
z=4/7x
x+y+z=913
x+4/5x+4/7x=913
by solving the equation ull get
x= 385
so by putting in it equation
z=4/7*385
z=220
