Africa.
Look at the world map carefully, it will be more easy to understand, for you.

Answer:

The continent that passes through the Tropic of Cancer, Tropic of Capricorn, and the Equator is Africa. Let's explore the reasons behind this:

Tropic of Cancer:
- The Tropic of Cancer is an imaginary line that lies at approximately 23.5 degrees north of the Equator.
- It is the most northerly latitude at which the sun can be directly overhead at noon.
- In Africa, the Tropic of Cancer passes through several countries such as Egypt, Algeria, Mauritania, Mali, Niger, Libya, and Chad.

Equator:
- The Equator is an imaginary line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere, with a latitude of 0 degrees.
- It is the line of latitude closest to the center of the Earth.
- The Equator passes through several African countries including Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, Somalia, and Maldives.

Tropic of Capricorn:
- The Tropic of Capricorn is an imaginary line located at approximately 23.5 degrees south of the Equator.
- It is the most southerly latitude at which the sun can be directly overhead at noon.
- In Africa, the Tropic of Capricorn passes through countries such as Namibia, Botswana, South Africa, Mozambique, and Madagascar.

Conclusion:
Taking into consideration the locations where the Tropic of Cancer, Tropic of Capricorn, and the Equator pass through, it can be concluded that the continent that is crossed by all three of these latitudes is Africa. The Tropic of Cancer passes through the northern part of the continent, the Equator runs through the central part, and the Tropic of Capricorn crosses the southern region.
