Question

A craft store has 8 feet of red ribbon. A customer bought 2 5/8

feet of red ribbon. How much red ribbon is left?

Answer 1

43/8 feet OR 5.375 feet

Explanation:

Initial length of the ribbon = 8 feet

Length of the ribbon the customer bought

= 2 ⅝

= (8 × 2) + 5/8

= 21/8

Remaining length of the ribbon

= 8 - 21/8

= 64/8 - 21/8

= 43/8 feet (in fractional form)

= 5.375 feet (in decimal form)

Hope it helps ⚜

Answer 2

5 3/8 or 43/8 feet

Explanation:

This question is asking for you to do the subtraction of fractions. To make this question easier, let's turn that mixed number (2 5/8) into an improper fraction. (Important:) So, multiply the denominator (8) by the whole number (2). From there, add the numerator (5) to what you already have. This will become your new numerator for this number, but make sure to keep the denominator the same. So:

2 5/8 = 21/8.

We also need to make the 8 an improper fraction as well, so that it is easier to solve. In order for the subtraction to be easiest, we need to make the 8 have the same denominator as the last improper fraction we created. So:

8 x 8 = 64, which means that (keeping the denominator) 8 = 64/8.

Now we can subtract. Subtract both numerators but keep the denominators.

64/8 - 21/8 = 43/8.

Now we need to turn this back into a mixed number. So, we need to divide the denominator (8) back into the numerator (43). After that, we get 5 with a remainder of 3/8.

I hope that this helps.
