To find the total number of smaller pieces we can obtain from the 7 inches ribbon we just need to divide.

Therefore, Leah would cut 14 smaller pieces of 1/2 inch long from a 7 inches ribbon.

So, the right answer is C.

14 pieces

Step-by-step explanation;

If Leah cuts a 7inch piece of ribbon into pieces that are 1/2inches each, to know the total number of pieces he cut, we only need to divide the 7inch piece by the 1/2 inch to have:

Total number of pieces = 7/(1/2)

Total number of piece = 7×2/1

Total number of pieces = 14 pieces

This means than Leah cuts the total number of 14pieces of ribbon

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
