Step-by-step explanation:

We need to do this in the order of PEMDAS

15-12+12÷3

Multiply and divide from left to right

15-12+4

Then add and subtract from left to right

3 +4

7

7

Step-by-step explanation:

Following PEMDAS, the first step is to divide 12 by 3. . The next step is to work from left to right. (15-12)+4=3+4=7. Hope this helps!

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

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.
