Answer:
By winning a global war against France.
Step-by-step explanation:
During the 1750s, the territories of the British and the French in North America were largely undefined. There were also several territorial disputes. However, soon some conflicts arose, giving rise to what is known as the French and Indian War. This war was part of the larger engagement known as the Seven Years' War. The war lasted from 1756 to 1763, with Great Britain resulting victorious. This victory allowed the British to become the dominant power in North America.
