It literally means "per hundred". So 70% is 70 per 100 which is 70 100. With algebra we use a letter to represent an unknown value. Let P be the percentage that 16 is of 64. Then we can write this as two fractions that equal each other: Now we want to "solve" this equation for P. That means we must multiply both sides of the equation by 100: This lets us cancel out the 100 in the denominator with the 100 we multiplied both sides of the equation by: Finally, we can divide 16 by 64 and then multiply by 100 on the right hand side to find the answer. So in this case 16 is 25% of 64. Your question can be solved exactly the same way, Art. Hope this helps,
