fabric (square meters) cloaks
7 21
4/3 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.
