Is 1,2,3,6,9 and 36 a múltiple of 9?

Answers

1 is not a multiple of 9.
2 is not a multiple of 9.
3 is not.
6 isn't either.

9 is a multiple of 9 because 9 x 1 = 9.
36 is a multiple of 9 because 9 x 4 = 36.
1 Is not a multiple of 9, nothing times 9 is 1.
2 Is not a multiple of 9, nothing times 9 gives 2.
3 Is not a multiple of 9, nothing times 9 gives 3.
6 Is not a multiple of 9, nothing times 9 is 6.
Those numbers are all less than 9.

9 is a multiple of 9 because 9 x 1 = 9.
36 is a multiple of 9 because 9 x 4 = 36.

The total capacity of 6 pitchers and 12 glasses is 21 liters. The capacity of a pitcher is 5 times that of a glass. Find the capacity of each glass. Give you answer in liters.

Answers

First you must set up an equation. Since there are 6 pitchers and 12 glasses you put. 6p + 12g = 21. Then they give you what p is (5g) and you plug that in and solve for g.

6(5g) + 12g = 21
30g + 12 g = 21
42 g = 21

Divide 42 on both sides to isolate the variable g. You get g = 0.5

The answer is that the capacity of each glass is 0.5 liters.

I don't know pls help

Answers

To divide fractions, we do Keep, Change, Flip. Keep means that we keep the first fraction the same ( which is 8/1). Then for Change, we change the division sign to a multiplication sign. After that we Flip the second fraction itś reciprocal (or multiplicative inverse).
So your equation would be:

8/1 x 3/1 which equals 24
