Answer:
The answer is sixty.
Step-by-step explanation:
In this problem, the number twenty-one represents the part.
So, let’s let x represent the unknown whole.
We can write a proportion showing that the ratio of the percent is equal to the ratio of the part to the whole.
Next, we find the cross products: thirty-five times x equals twenty-one times one hundred, and set cross products equal.
Now we can divide both sides of the equation by thirty-five.
Finally, we can simplify each side and find that the value of x is sixty.
So, twenty one is thirty-five percent of sixty.
