a telephone pole is 64 feet long and 5/16
of the pole must be underground
a) what fraction of the pole is above ground
16/16 - 5/16 = 11/16
To find the fraction of the pole that is above ground, we need to subtract the fraction that is underground from 1 (which represents the whole pole).
Given that 5/16 of the pole is underground, we can represent this fraction as 5/16. Therefore, the fraction above ground would be 1 - 5/16.
To subtract fractions, we need to find their common denominator. The least common multiple of 16 and 1 is 16.
Now, let's convert both 1 and 5/16 to fractions with a denominator of 16:
1 = 16/16
5/16 remains the same.
Subtracting fractions, we have:
16/16 - 5/16 = (16 - 5)/16 = 11/16
Therefore, 11/16 of the pole is above ground.
