A machine shop bought 14 steel rods of [tex]\frac{7}{8}[/tex]-in.-diameter steel, 23 rods of [tex]\frac{1}{2}[/tex]-in. diameter, 8 rods of [tex]\frac{1}{4}[/tex]-in. diameter, and 19 rods of 1-in. diameter. How many rods were purchased?



Answer :

Sure, let's solve this problem step-by-step.

To determine the total number of steel rods purchased by the machine shop, we need to sum the quantities of rods for each diameter.

1. Number of rods of [tex]\( \frac{7}{8} \)[/tex]-in. diameter:
There are 14 rods of [tex]\( \frac{7}{8} \)[/tex]-in.-diameter.

2. Number of rods of [tex]\( \frac{1}{2} \)[/tex]-in. diameter:
There are 23 rods of [tex]\( \frac{1}{2} \)[/tex]-in.-diameter.

3. Number of rods of [tex]\( \frac{1}{4} \)[/tex]-in. diameter:
There are 8 rods of [tex]\( \frac{1}{4} \)[/tex]-in.-diameter.

4. Number of rods of 1-in. diameter:
There are 19 rods of 1-in.-diameter.

Now, to find the total number of rods, we will add these quantities together:

[tex]\[ 14 + 23 + 8 + 19 \][/tex]

Let's perform the addition step-by-step:

[tex]\[ 14 + 23 = 37 \][/tex]

[tex]\[ 37 + 8 = 45 \][/tex]

[tex]\[ 45 + 19 = 64 \][/tex]

Therefore, the total number of rods purchased by the machine shop is 64.
