$\text{Answer: }46(2)/(7)\text{ yards is needed to make 9 pillow covers.}$

Explanation:

Since we have given that

Material needed to make a pillow cover is given by

$5(1)/(7)\ yards=(36)/(7)\ yards$

We need to calculate the material which will be needed to make 9 pillows covers.

So, we use the "Multiplication Operation" as we need the value for more pillow covers :

$9* (36)/(7)\\\\=(324)/(7)\\\\=46(2)/(7)\ yards$

$\text{Hence, }46(2)/(7)\text{ yards is needed to make 9 pillow covers.}$
