Ben and Cam are scuba diving. Ben is 15.815.815, point, 8 meters below the surface of the water. Cam is 4.24.24, point, 2 meters
alexira [117]

Answer:

Cam is at 6m below the surface of the water.

Step-by-step explanation:

Ignore all info except:

Ben is 8 meters below the surface of the water.

Cam is 2 meters above Ben

So now answer this;

What is Cam's position relative to the surface of the water?

This is too simple. Cam is 2 m above Ben which means two meter closer to the surface as Ben.

Ben was 8 m below the surface. By this Cam is 2 m closer to the surface, which is 8 - 2 = 6 m.

Cam is at 6m below the surface of the water.

The ratio of black marbles to red marbles is 3:2. If there are a total of 25 marbles in a bag,
kumpel [21]

Answer:

15 black marbles

Step-by-step explanation:

So its. A ratio (basically a fraction)

3/2

we add them up so we know how much marbles but not which kind

so we get 5

now we know for every 5 batches there is 3 black and 2 red

so we divide 25/5 to get 5

now we know there are 5, 5 batches of black ad red marbles.

now black is 3 of them so we multiply 5(3) which is 15

Now red is 2 of them so we multiply 5(2). Which is 10

now to check, if we add them up, they equal to 25 which is correct.

basically add the fraction, divide that by the original number, time the quotient by each number in the fraction.
