I'm doing a problem, and it says "Robert has a piece of twine that is 3/4 yard long. He needs a piece of twine that is 2/3 of this length. How long of a piece of twine does robert need?"
Help?
Multiply 3/4 by 2/3 to get the piece Robert needs:
(3/4) * (2/3) = ?
If you don't have a calculator, cross multiply so the 3s cancel out and the 2 goes into the 4 twice...leaving you with an answer of?
So it would be half of his piece?
Yep! :)
Thank you!
:)
I mean the piece he has is 1/2 yard long, not half of the 3/4-yard one. oops sorry! lol
You're welcome! :)
To find out how long of a piece of twine Robert needs, you need to multiply the length of the original twine by 2/3.
Here are the steps to solve the problem:
Step 1: Determine the length of the original twine.
Robert has a twine that is 3/4 yard long.
Step 2: Multiply the length of the original twine by 2/3.
(3/4) * (2/3)
Step 3: Simplify the multiplication.
To multiply fractions, multiply the numerators together and the denominators together. This gives us:
(3 * 2) / (4 * 3) = 6/12
Step 4: Simplify the fraction.
Since both the numerator and the denominator can be divided by 6, we get:
6/12 = 1/2
Therefore, Robert needs a piece of twine that is 1/2 yard long.
