Explanation:
Given;
- 4/9 = 12/_ = 40/90 = _/108
Let us take the first number x and second be y
So,
4/9 = 12/x = 40/90 = y/108
Now,
4/9 = 12/x
4x = 12(9)
4x = 108
4x/4 = 108/4
x = 27
Now,
40/90 = y/108
4/9 = y/108
4(108) = 9y
432 = 9y
9y = 432
9y/9 = 432/9
y = 48
Now,
4/9 = 12/x = 40/90 = y/108
4/9 = 12/27 = 40/90 = 48/108 = 0.44
