Answer: B = 0.7 because 5.6 divided by 8 equals 0.7! Hope this helpz...

Answer: B = .7

Explanation: Since we are doing multiplication (8 * b) we would now do the inverse operation which is dividing. First, it's 5.6 divided by itself so we can cross that out, then 8 divided by 5.6 = .7

If we put 8 * .7 in a calculator, sure enough, it comes out as 5.6

A chess player played 20 games total. If he won 2 of the games, what is the ratio of games he lost to games he won?

So, we have useful information to answer this question. We know that he played 20 games and he won 2 games. To find the ratio of the games lost, we have to subtract the number of games played and the number of games won.

20-2=18

So now we can find the ratio of games won and games lost

The answer is 18:2, 18 to 2, or 18/2.

You can also simplify the ratio to 9:1

So the final answer is 9:1
