Question

Martin sorted the bolts in his toolbox by size. They measured 3/8 inch, 1/2 inch,5/8 inch, 7/8 inch, and 1 1/4 inches . What is the difference in length between the longest bolt and the shortest bolt? If you laid one of each size bolt end to end , how long would the row of bolts be?

Answer 1

1 1/4=5/4=10/8 and 10/8-3/8 is 7/8

Answer 2

Length between the longest bolt and the shortest bolt is:

2.375 inch

If we laid one of each size bolt end to end , then the length of row of bolts is:

5.125 inch

Explanation:

We are given that:

Martin sorted the bolts in his toolbox by size.

They measured 3/8 inch, 1/2 inch,5/8 inch, 7/8 inch, and 1 1/4 inches

longest bolt= 11/4 inches shortest bolt=3/8 inch

Difference between longest and shortest bolt=
`(11)/(4) - (3)/(8)\\ \\=(22-3)/(8)\\ \\=(19)/(8)\\ \\= 2.375`

Now, if we lay one of each size bolt end to end then, length of row will be:

`(3)/(8)+(1)/(2)+(5)/(8)+(7)/(8)+(11)/(4)`

=41/8

= 5.125 inches
