13 is 26 percent of 50.
To determine the number that 13 is 26% of, we can set up the equation:
13 = 0.26x
Here, x represents the unknown number we are trying to find. To solve for x, we divide both sides of the equation by 0.26:
13 / 0.26 = x
Simplifying the expression, we have:
x = 50
Therefore, 13 is 26% of 50.
To understand this calculation, we recognize that 26% can be expressed as the decimal 0.26. Multiplying 0.26 by the unknown number x gives us 13, which means that 13 is 26% of x. By dividing both sides of the equation by 0.26, we isolate x and find that it is equal to 50.
