Reduce the number 16 in proportion
3:2
5:4
11:8

Result

a =  10.667
b =  12.8
c =  11.636

Solution:


16 = 3:2 * a

1.5a = 16

a = 323 ≈ 10.666667

Calculated by our simple equation calculator.


16 = 5:4 * b

1.25b = 16

b = 645 = 12.8

Calculated by our simple equation calculator.


16 = 11:8 * c

1.375c = 16

c = 12811 ≈ 11.636364

Calculated by our simple equation calculator.
