Answer: The number that goes in the green box is 7
Step-by-step explanation: The LHS of the equation can also be expressed as,
x/ (7/8) OR
x times (8/7)
That is, 8x/7
In other words, the equation now becomes;
8x/7 = 2/3
By cross multiplication we now have
8x(3) = 7(2)
24x = 14
Divide both sides of the equation by 24
x = 14/24
(Simplified further)
x = 7/12
Therefore the number that goes in the green box is 7.
