Question

Ed had a piece of rope 6 3/4 ft long. he cut of 3/8 ft. how much rope did ed have left? enter you answer in the box as a mixed number in simplest form

Answer 1

Let's first convert the first number to an improper fraction so we can perform arithmetic on it:

`6(3)/(4) =(27)/(4)`

Now, let's get common denominators. Since 3/8 has a denominator of 8, we can multiply our, newly found, improper fraction by 2 to get a denominator of 8:

`(27)/(4) *2=(54)/(8)`

Next, subtract (because Ed cuts the rope):

`(54)/(8) -(3)/(8) =(51)/(8)`

Last step is to convert it back into a mixed fraction:

`(51)/(8) =6(3)/(8)`

So, your final answer is 6 and 3/8. Hope I could help, and let me know if I can do anything else for you! :)
