Question

Ed needed to extend the string on his kite. the current string was seven and three fourths feet. he cut a piece of string that measured 8.5 feet and added it to the existing string. what is the new length of the string? fifteen and three fourths feet sixteen and one fourth feet three and one half feet three and one fourth feet

Answer 1

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)
