1. 18 + 24 = 6 * (3 + ?) 2. 10 + 2 = ? (5 + 1) 3. 3 x (7 + ?) = 21+ 6 4. ? x (3 + 2) = 12 + 8 5. 30 + 28 = 2 * (15 + ?) Please give me the numbers for the question marks

step-by-step explanation:

3

step-by-step explanation:

ok so what's the question?

step-by-step explanation:

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.
