Problem: a certain galaxy is known to comprise approximately 5 x 10 ^ 11 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 ?
Rationale: "total no . of stars on galaxy = 5 * 10 ^ 11 of every 50 million stars , 1 is larger than sun . 1 million = 10 ^ 6 therofore , 50 million = 50 * 10 ^ 6 total no . of stars larger than sun = 5 * 10 ^ 11 / 50 * 10 ^ 6 = 50 * 10 ^ 3 / 5 = 10000 therefore answer is e"
