A Medium Sandwich at Heidi's Heroes: A Math Problem

Understanding the Problem

When it comes to comparing the lengths of sandwiches, we need to consider the units of measurement. In this problem, we have a medium sandwich that is $\frac{5}{8}$ foot long, and a small sandwich that is $4 \frac{7}{8}$ inches long. Our goal is to determine how many inches longer the medium sandwich is than the small sandwich.

Converting Feet to Inches

To compare the lengths of the two sandwiches, we need to convert the length of the medium sandwich from feet to inches. Since there are 12 inches in a foot, we can multiply the length of the medium sandwich by 12 to get its length in inches.

$\frac{5}{8} \text{ foot} \times 12 \text{ inches/foot} = \frac{5}{8} \times 12 = 7.5 \text{ inches}$

Comparing the Lengths of the Sandwiches

Now that we have the length of the medium sandwich in inches, we can compare it to the length of the small sandwich. The small sandwich is $4 \frac{7}{8}$ inches long, which is equal to $4.875$ inches.

To find the difference in length between the two sandwiches, we can subtract the length of the small sandwich from the length of the medium sandwich.

$7.5 \text{ inches} - 4.875 \text{ inches} = 2.625 \text{ inches}$

Simplifying the Answer

We can simplify the answer by converting the decimal to a fraction. Since $2.625$ is equal to $\frac{21}{8}$ , we can write the answer as a fraction.

$\frac{21}{8} \text{ inches}$

Converting the Fraction to a Mixed Number

To make the answer more understandable, we can convert the fraction to a mixed number. Since $\frac{21}{8}$ is equal to $2 \frac{5}{8}$ , we can write the answer as a mixed number.

$2 \frac{5}{8} \text{ inches}$

Conclusion

In conclusion, the medium sandwich at Heidi's Heroes is $2 \frac{5}{8}$ inches longer than the small sandwich.
