consumption, using 97.6 quadrillion british thermal units (btu). what was the world's energy consumption in 2002?

The answer to your question: World's energy = 4.15 x 10 ¹⁶ BTU

Step-by-step explanation:

USA energy = 23.5%

BTU = 97.6 quatrillion = 97600000000000000

World's energy consumption = ?

1 quatrillion = 1 000 000 000 000 000

      9760000000000000    23.5%

                  x                              100%

x = 100 x  9760000000000000 / 23.5

X = 4.15 x 10 ¹⁶ BTU
