Understanding the Problem

Tina is a crafty individual who wants to sew her own dress. She has purchased 4.5 meters of material, which costs $8.50 per meter. To determine the total cost of the material, we need to calculate the amount of material Tina will use to sew her dress.

Calculating the Amount of Material Used

Tina plans to use $\frac{3}{5}$ of the material she purchased. To find out how many meters of material she will use, we need to multiply the total amount of material purchased by the fraction she plans to use.

Step 1: Multiply the Total Amount of Material Purchased by the Fraction

The total amount of material purchased is 4.5 meters. The fraction Tina plans to use is $\frac{3}{5}$ . To multiply a decimal by a fraction, we can multiply the decimal by the numerator and then divide by the denominator.

# Define the total amount of material purchased total_material = 4.5 fraction_used = 3/5

material_used = total_material * fraction_used

Step 2: Calculate the Amount of Material Used

Now that we have multiplied the total amount of material purchased by the fraction, we can calculate the amount of material Tina will use.

# Calculate the amount of material used
material_used = 4.5 * (3/5)
material_used = 2.7

Conclusion

Tina will use 2.7 meters of material to sew her dress.

Discussion

This problem requires the application of multiplication and fractions to calculate the amount of material used. Tina's decision to use $\frac{3}{5}$ of the material she purchased is a common scenario in real-life situations, such as sewing, carpentry, or construction. Understanding how to calculate the amount of material used is essential in these fields to ensure accurate estimates and avoid waste.

Real-World Applications

Calculating the amount of material used has numerous real-world applications. In construction, architects and engineers need to calculate the amount of materials required for a project to ensure accurate estimates and avoid waste. In sewing, crafters need to calculate the amount of fabric required for a project to ensure they have enough material to complete the task.

Tips and Tricks

When working with fractions, it's essential to remember that a fraction is a way of expressing a part of a whole. In this problem, the fraction $\frac{3}{5}$ represents the part of the material Tina plans to use. To multiply a decimal by a fraction, we can multiply the decimal by the numerator and then divide by the denominator.

Common Mistakes

When working with fractions, it's common to make mistakes when multiplying decimals by fractions. To avoid this, make sure to multiply the decimal by the numerator and then divide by the denominator.

Conclusion
