Jessi has 9 feet of blue fabric. She need one third of that amount in red fabric. The fabric store sells fabric by the yard. How much fabric does Jessie need to buy?

1 yard

Step-by-step explanation:

Let b represent the amount of blue fabric and r represent the amount of red fabric.

Given;

Jessi has 9 feet of blue fabric

b = 9 ft

She need one third of that amount in red fabric.

r = 1/3 * b

Substituting the value of b;

The amount of red fabric needed r is;

r = 1/3 * 9 = 3 ft

Since they sell in yards, we need to convert it to yards.

1 yard = 3 feets

Therefore,

r = 3 ft * 1/3 yard per ft

r = 1 yard
