Question

Alyssa uses the fabric to make pillowcases. Each pillowcase uses 1.9 square meters of fabric. Using a bolt of her fabric, Alyssa can make how many pillowcases.

Answer 1

To determine how many pillowcases Alyssa can make, divide the total area of the fabric bolt by 1.9 square meters. This requires simple arithmetic and an understanding of area calculations in the context of fabric and textiles.

Step-by-step explanation:

How many pillowcases can be made from a bolt of fabric requires a mathematical calculation involving area and division. To solve this problem, Alyssa simply needs to divide the total area of fabric in the bolt by the area required for one pillowcase, which is 1.9 square meters. This is a typical arithmetic problem, which falls under the category of practical applications of mathematics often seen in textile and fabric-related problems.

Additionally, understanding the importance of specifying units when discussing measurements, as in the case of buying fabric for curtains, further illustrates the everyday relevance of mathematical concepts. Furthermore, studies on the efficiency of design and materials, such as the household aluminum foil investigation or the history of quilt making, showcase the interplay between mathematics, engineering, and art.

Answer 2

Using division and given that the area of a bolt of wool is 139.355 m², Alyssa can make 73 pillowcases using a bolt of her fabric.

Division operation is one of the four basic mathematical operations. Others include addition, subtraction, and multiplication.

Division operation involves the dividend, the divisor, and the quotient, being the result of the operation.

The area of a bolt of wool = 139.355 m²

The requirement for a pillowcase = 1.9 m²

The number of pillowcases Alyssa can make = 73.34 (139.355 m² ÷ 1.9 m²)

Thus, we can conclude that Alyssa can make 73 pillowcases.
