==========================================================

Explanation:

For each column, we divide the values by the sum of each column.

The sum of the first column is 6+8 = 14, and the sum of the second column is 7+3 = 10.

Column 1:

6/14 = 0.43
8/14 = 0.57

Those values are approximate to two decimal places.

Column 2:

7/10 = 0.70
3/10 = 0.30

Those values are exact.

The values in bold are then filled in the table as you see below.

A result like 0.43 means that 43% of those who play a sport also play an instrument. The other values are interpreted in a similar fashion.

How can we change 1 litre into 1000cm3

vekshin1

1 litre is equal to 1000cm³.

To change from litres into cubic centimetres, you times the value by 1000.

Eg:
Imagine the question “turn 5 litres into cm³”

First step would be to figure out how many litres we have, which is 5.

Now, we multiply 5 by 1000, which gives us 5000.

Therefore 5 litres = 5000cm³

I hope this helps and made sense, if you have any more questions or need me to explain further, just ask! :)
