A certain galaxy is known to comprise approximately 4 x 1011 stars. Of every 50 million of these stars, one is larger in mass than our sun. Approximately how many stars in this galaxy are larger than the sun?

8000 stars in this galaxy are larger than our sun

Step-by-step explanation:

Number of stars in the galaxy = 4*10^11

Number of star larger than the sun in every 50*10^6 stars in the galaxy = 1

Number of stars in the galaxy that are larger than the sun = (4*10^11) : (50*10^6) = 8000
