A piece of fabric is 1/3 yard by 3 5/8 yards. Irma solves 1/3⋅3 5/8 to find the area of the fabric in square yards. Enter number
Harlamova29_29 [7]

For this case we have:


The area of the piece of fabric is given by A = a * b


Where


a = \frac{1}{3}yards


b = 3 \frac{5}{8}yards


Substituting in the formula of the area we have:


A = \frac{1}{3}* 3 \frac{5}{8}\\

A = \frac{1}{3}* (3 + \frac{5}{8})\\

A = 1 + \frac{5}{24}


A = 1\frac{5}{24}yards ^ 2\\

Thus, the area of the piece of fabric is given by: A = 1\frac{5}{24}yards ^ 2\\

Answer:


A = 1\frac{5}{24}yards ^ 2\\
