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


X=200

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.
