The coldest temperature on earth was −128.6°F, measured at the World Meteorological Organization recognized Vostok Station in Antarctica on July 21, 1983. Neptune's largest moon, Triton, dropped to a bone-chilling -391°F, making the moon colder than Neptune. What is the difference of the coldest temperatures between Earth and Triton?
-128.6 - (-391) = - 128.6 + 391
262.4 degrees

Solve. Simplify if needed.
- 3/5 + 2/10 - 4/10
2/10 - 4/10 = -2/10
Reduce -2/10 to -1/5
-3/5 -1/5 = -4/5
Answer is -4/5
or reduce the last two fractions and go from there.
