6 rectangle and 9 triangle

Step-by-step explanation:

Cora makes a scarf with rectangle and triangle clothes.

For every 5 pieces of cloth, 2 are rectangles.

The ratio that Cora uses 2 : 3

She needs 15 pieces of cloth to complete her scarf.

Let the number x is multiplier of the ratio. Now the equation will be

2x + 3x = 15

5x = 15

x =  

x = 3

Now we will multiply the ratio by 3

2x = 2(3) = 6

3x = 3(3) = 9

She will use 6 rectangle and 9 triangle clothes.
