Answer:
X=200
Explanation:
56/x = 28/100
cross multiply 56*100 and 28*X
you get 5600 = 28x
reduce them by dividing both by 7, resulting in
800 = 4x
divide both sides by 4 and switch sides
200 = X
Change 28% to a decimal by moving the decimal point 2 places to the left:
28% = 0.28
Write the question as an equation to get:
56 = 0.28x
Now to solve for x, divide both sides by 0.28:
x = 56 / 0.28
x = 200
The unknown number is 200.
