robert has a piece of twine 3/4 yards long. he needs a piece of twine that is 2/3 of this length. how long of a piee of twine does robert need?
To find the length of the twine that Robert needs, we can multiply the length of his original piece of twine by 2/3.
First, let's convert the length of the original twine from yards to a fraction. Since we know that 1 yard is equal to 3 feet, we can say that 3/4 yards is equal to (3/4)*3 = 9/4 feet.
Now, we can multiply 9/4 feet by 2/3 to find the length of the twine that Robert needs.
(9/4) * (2/3) = (9*2)/(4*3) = 18/12 = 3/2 feet.
Therefore, Robert needs a piece of twine that is 3/2 feet long.
