Divide 7.8 by 1.18:
7.8 / 1.18 = 6.61 = 6.6 rounded to the nearest tenth.
When you divide scientific notation, subtract the exponents: 20 - 13 =7
The answer becomes 6.6 x 10^7
Division is one of the four fundamental arithmetic operations. The number of times the milk way is wider than the solar system is 6.61 × 10⁷.
What is Division?
The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that our solar system is 1.18 × 1013 meters in diameter, and the Milky Way galaxy is 7.8 × 1020 meters in diameter. Therefore, the number of times the milk way is wider than the solar system is,
Number of times = (Diameter of MIlky way)/(Diameter of Solar System)
= 7.8 × 10²⁰ meters/ 1.18 × 10¹³ meters
= 6.61 × 10⁷
