There are red, blue and green candies in bad. Red to green is in 6:11 ratio and blue to red in a 7: 5 ratio. In what proportion are blue to green candies?

Result

p =  42:55

Solution:

r:g=6:11 b:r=7:5 p=b:g=?  g=11:6 r b=7:5 r  p=6 711 5=42550.76360.763642:55r:g=6:11 \ \\ b:r=7:5 \ \\ p=b:g=? \ \\ \ \\ g=11:6 \ r \ \\ b=7:5 \ r \ \\ \ \\ p=\dfrac{ 6 \cdot \ 7 }{ 11 \cdot \ 5 }=\dfrac{ 42 }{ 55 } \doteq 0.7636≈ 0.7636 \doteq 42:55
