Iris is asked to sweep the gymnasium floor after a basketball game. This requires her to push a sweeper from one end of the gym to the other and repeating the pattern until she has covered the entire floor. She completes 2/3 of the floor in 1/3 of an hour. At this rate, how long will it take her to complete the entire floor?(1 point)

To find out how long it takes Iris to complete the entire floor, we can set up a proportion.
Let x be the time it takes for her to complete the entire floor.
We know that Iris completes 2/3 of the floor in 1/3 of an hour, so we can set up the proportion:
(2/3) / (1/3) = 1 / x
Simplifying the left side of the equation:
(2/3) * (3/1) = 1 / x
2 = 1 / x
To solve for x, we can take the reciprocal of both sides:
1/2 = x
So, it will take her 1/2 hour or 30 minutes to complete the entire floor.
Therefore, the answer is 1/2 hours.
Find the quotient of 12 and 127 .
To find the quotient of 12 and 127, divide 12 by 127:
12 รท 127 = 0.09448818898 (rounded to the nearest ten-thousandth)
The quotient is approximately 0.0945.
To find out how long it will take Iris to complete the entire floor, we can use the information provided.
We know that Iris completes 2/3 of the floor in 1/3 of an hour.
To find out how long it will take her to complete the entire floor, we can set up a proportion using the fraction of the floor completed and the time taken.
Let "x" represent the time it will take her to complete the entire floor.
So we have:
2/3 (fraction of the floor completed) = 1/3 (time taken)
To find "x," we can cross multiply and solve for it:
2/3 * x = 1/3 * 1
Multiplying both sides by 3/2, we get:
x = 1/2
Therefore, it will take Iris 1/2 hour to complete the entire floor.
So the correct answer is "1/2 hours" or "Start Fraction 1 over 2 End Fraction hours."
