Answer 1

(A) 9.3 × 10⁶ and 1.9 × 10⁶

(B) Percentage of young visitors ≈ 2.04 × 10¹ %

Explanation:

Part A:

To write the numbers in scientific notation, we need to express them in the form of a number between 1 and 10 multiplied by a power of 10.

1. The number of visitors to the Louvre each year, 9,300,000, can be written in scientific notation as 9.3 × 10⁶.
2. The number of young people visiting the Louvre each year, 1,900,000, can be written in scientific notation as 1.9 × 10⁶.

Part B:

To find the percentage of visitors who are young people, we can divide the number of young visitors by the total number of visitors and then multiply by 100.

Percentage of young visitors = (Number of young visitors / Total number of visitors) × 100

Percentage of young visitors = (1,900,000 / 9,300,000) × 100

Calculating this, using a calculator:

=> Percentage of young visitors ≈ 0.204 × 100

=> Percentage of young visitors ≈ 20.4%

Expressing the percentage in scientific notation, we get:

=> Percentage of young visitors ≈ 2.04 × 10¹%
