50% of 36 means a half of 36 which is 18
In mathematics, 'is' would be the equal sign. And 'of' would be the multiplcation sign. The missing number would be any variable.

Solving for x, we get:

Divide 28 on both sides

Multiply 100 on both sides
56 is 28% of 200
24:16 which is simplified by dividing both sides by 8 so it becomes:
3:2
Hope this helps :)
