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:

$6\frac{3}{4} =\frac{27}{4}$

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:

$\frac{27}{4} *2=\frac{54}{8}$

Next, subtract (because Ed cuts the rope):

$\frac{54}{8} -\frac{3}{8} =\frac{51}{8}$

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

$\frac{51}{8} =6\frac{3}{8}$

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! :)
