Answer:

There are 20 kids total in the class.

Step-by-step explanation:

15/100 × 20 = 3  

You can use direct proportion for any percent calculation.

Compare each number with its percent.

3 i s  15 %  of what number? Let the number be  x

So, 3  represents  15 %  and  x  represents  100 %

x/ 100   =  3/15  

Multiply by  100  to isolate  x

x  = \frac{3 x 100}{15}

x  =  20

Check:  15/ 100 × 20 = 3

How many 1/3 cups of ice cream can you make from 1/7 cup
OlgaM077 [116]
Well first you have to make the denominators equal by finding a common denominator. in this case 21, but whatever you do to the bottom you do to the top. so 1/3 times 7/7 equals 7/21 and 1/7 times 3/3 equals 3/21.
 
so how many 7/21 cups of ice cream can you make from 3/21 i think  about none but remember i could be wrong

Easy bruh

Answer:

6w^3

Step-by-step explanation:

It can't be any answer with cubed in it because that would be volume. So, A and C magically vanish. If we know that the length of a cube is w that means that all sides are w. There are six faces on a cube. If we want to find surface area we will have to add up the area of all faces. the area of one face will be w^2. We multiply that number by six and we get 6w^3.
