The new length of the string is (16 + 1/4) feet, then the correct option is the second one (counting from the top)

We know that the current string was (7 + 3/4) feet in length. Then they add another piece that measures 8.5 feet.

The new length of the string is given by the addition of the above two lengths, we will get:

L = (7 + 3/4) feet + 8.5 feet

We can rewrite the second length as a mixed number:

8.5 = 8 + 1/2 = 8 + 2/4

Replacing that we get:

L = (7 + 3/4) ft + 4.5 ft

= (7 + 3/4) ft + (8 + 2/4) ft

= (7 + 8) ft + (3/4 + 2/4) ft

= 15ft + 5/4ft = 15ft + (4/4 + 1/4)ft = (16 + 1/4)ft

The new length of the string is (16 + 1/4) feet, then the correct option is the second one (counting from the top)
