What is the answer to 56 is 28% of

klio [65]

In mathematics, 'is' would be the equal sign. And 'of' would be the multiplcation sign. The missing number would be any variable.

56 is 28% of a number would be translated algebraically to:

$56 = \frac{28}{100} \times x$

Solving for x, we get:

$56 = \frac{28}{100} \times x$

Divide 28 on both sides

$2 = \frac{x}{100}$

Multiply 100 on both sides

$x = 200$

56 is 28% of 200
