Final answer:
Comparing a country's exports to its GDP indicates its degree of globalization, with a higher ratio suggesting more global integration. Canada had an export ratio of 30.11% when its GDP was $1,800 billion and exports were $542 billion.
Step-by-step explanation:
Comparing a country's exports to its GDP is a crucial metric that reflects its degree of globalization. This export ratio signifies what share of a country's total economic production is sold in other countries, indicating the extent of its integration with the global economy. Countries with a high percentage of exports relative to their GDP, like Germany, demonstrate a high level of trade and globalization, while countries with a lower percentage, such as the United States, which exports around 13% of its GDP, show a smaller degree of economic globalization.
To calculate Canada's export ratio, we use the given figures: Canada's GDP was $1,800 billion and its exports were $542 billion. By dividing the exports by the GDP and then multiplying by 100, we get the export ratio: ($542 billion ÷ $1,800 billion) × 100 = 30.11%. So, Canada had an export ratio of 30.11% at that time.
