What is a fraction of the sun's diameter?

The diameter of the sun is approximately 1.4 million kilometers. If we want to express a fraction of the sun's diameter, we would need to specify the numerator (the part we are interested in) and the denominator (the total diameter of the sun). For example, if we were interested in one-tenth of the sun's diameter, the fraction would be 1/10, which would equate to 140,000 kilometers.
