A garden hose has an outside diameter of 1 1/4 inches. Its inside diameter is 1 inch. How thick is the hose?
(1/4)/2 = 1/8 inch
To find the thickness of the hose, we subtract the inside diameter from the outside diameter.
The outside diameter is given as 1 1/4 inches. To subtract the inside diameter of 1 inch from this, we need to convert 1 1/4 inches to an improper fraction so that we can subtract the fractions.
To convert 1 1/4 to an improper fraction, we multiply the whole number (1) by the denominator of the fraction (4) and add the numerator (1), then put the result over the denominator:
(1 * 4 + 1) / 4 = 5/4
So, the outside diameter is 5/4 inches and the inside diameter is 1 inch.
To find the thickness of the hose, we subtract the inside diameter (1 inch) from the outside diameter (5/4 inches):
5/4 inches - 1 inch = 5/4 - 4/4 = (5 - 4)/4 = 1/4 inches
Therefore, the thickness of the hose is 1/4 inch.
