For this case, the first thing we are going to do is define variables:
x: size of the radius of the star
Y: size of the solar radio.
Let's write an equation that models the problem:
a star has a size of 0.1 solar radius:
\(x = 0.1y\)
Clearing y we have:
\(y = x / 0.1\)
Rewriting we have:
\(y = x / (1/10)
y = 10x\)
Answer:
the sun is 10 times larger than this star
