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

Answer:

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

Step-by-step 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=  $\dfrac{11}{4} - \dfrac{3}{8}\\ \\=\dfrac{22-3}{8}\\ \\=\dfrac{19}{8}\\ \\= 2.375$

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

  $\dfrac{3}{8}+\dfrac{1}{2}+\dfrac{5}{8}+\dfrac{7}{8}+\dfrac{11}{4}$

=41/8

= 5.125 inches
