A flagpole 6.3m long is driven 1.4m into the ground. What fraction of the pole is above the ground?
To find the fraction of the pole that is above the ground, we need to divide the length of the portion of the pole above the ground by the total length of the pole.
The length of the portion of the pole above the ground is the total length of the pole minus the length of the portion of the pole that is driven into the ground:
Length above ground = 6.3m - 1.4m = 4.9m
Now we can calculate the fraction of the pole that is above the ground by dividing the length above the ground by the total length of the pole:
Fraction above ground = Length above ground / Total length
Fraction above ground = 4.9m / 6.3m
Simplifying the fraction:
Fraction above ground = 49/63
So, the fraction of the pole that is above the ground is 49/63.
To determine the fraction of the pole that is above the ground, we need to find the difference between the length of the pole and the portion of the pole driven into the ground, and then express it as a fraction of the total length.
Length above ground = Total length - Length driven into the ground
Length above ground = 6.3m - 1.4m
Length above ground = 4.9m
To express this as a fraction of the total length:
Fraction above ground = Length above ground / Total length
Fraction above ground = 4.9m / 6.3m
Simplifying the fraction, we get:
Fraction above ground = 49/63
Therefore, approximately 77.8% of the pole (or about 49/63) is above the ground.
To determine the fraction of the flagpole that is above the ground, we need to find the length of the pole above the ground and then divide that by the total length of the pole.
To find the length of the pole above the ground, we can subtract the depth it is driven into the ground from the total length of the pole. In this case, the pole is 6.3m long and driven 1.4m into the ground:
Length above the ground = Total length of the pole - Depth driven into the ground
Length above the ground = 6.3m - 1.4m = 4.9m
Now, to determine the fraction of the pole above the ground, we divide the length of the pole above the ground by the total length of the pole:
Fraction above the ground = Length above the ground / Total length of the pole
Fraction above the ground = 4.9m / 6.3m
To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 0.1:
Fraction above the ground = (4.9m / 0.1) / (6.3m / 0.1)
Fraction above the ground = 49 / 63
Therefore, the fraction of the flagpole above the ground is 49/63.
