The 250 pounds of food will last for 20.83 days.
An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
Initial quantity of food = 250 pounds,
Since, mountain climbers begin to eat 12 pounds per day,
Let the food will last for x days,
The equation can be written as,
12x = 250
x = 20.833
The food will last for 20.83 days.

The fraction as an improper fraction is 38/9
From the question, we have the following parameters that can be used in our computation:
Fraction = 4 2/9
When converted to an improper fraction, we have
Numerator = 9 * 4 + 2
Evaluate
Numerator = 38
The denominator remains the same
So, we have
Fraction = 38/9
Hence, the fraction is 38/9
