Fabric (square meters)                   Cloaks

7                                                          21

                                                        4

Step by step explanation:

We are told that Harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. First of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

We can see that 3 cloaks can be made from 1 square meter of fabric. Now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

Therefore, Harry will make 21 cloaks from 7 square meters of fabric.

2. Let us find how many square meters of fabric will be needed to make 4 cloaks.

First of all we will find fabric needed for 1 cloak by dividing 2 by 6.

We can see that fabric needed for 1 cloak is square meter. Now we will multiply by 4 to find fabric needed for 4 cloaks.

Therefore, Harry will need square meters of fabric to make 4 cloaks.
