Math Problem Statement
Ed needed to extend the string on his kite. The current string was eight and three fourths feet. He cut a piece of string that measured 4.5 feet and added it to the existing string. What is the new length of the string?
Solution
To find the new length of the string after Ed adds the additional piece, we need to add the length of the existing string to the length of the added string.
The current string length is 8 and 3/4 feet, which can be written as a mixed number: We can convert this mixed number into an improper fraction:
The additional string length is given as 4.5 feet. We can convert 4.5 into a fraction:
Now, let's add these two fractions:
To add these fractions, we need a common denominator. The least common denominator between 4 and 2 is 4. We convert to :
Finally, we can convert back into a mixed number:
So, the new length of the string is 13 and 1/4 feet.
