Question

Charles measured three pieces of string.The strings measured 7.68 inches,3.9 inches,and 2.2 inches.What is the difference in length between the longest string and the shortest string

Answer 1

5.48

Explanation:

Given length of three strings:

`\text{Length of first string}, L_1=7.68\ inches\\\text{Length of second string}, L_2=3.9\ inches\\\text{Length of third string}, L_3=2.2\ inches`

To find:

The difference in length between the longest and the shortest string?

Solution:

First of all, let us compare the given three decimal numbers.

We check the number before decimal first of all.

We can see that the numbers are 7, 3, and 2.

7 being the largest
`L_1` is the longest string.

2 being the smallest
`L_3` is the shortest string.

So, the difference is:

`L_1-L_3=7.68-2.2\\\Rightarrow \bold{L_1-L_3=5.48 }`

So, the answer is 5.48.
