Answer: 3/4

Step-by-step explanation:

If  Jamal has 3 times as many cars as  planes then we could represent it by the equation   x + 3x = 20  where x is the number of planes  and 3x is the number of cars.

x+ 3x =20   solve for x

4x = 20

x = 5    

Number of planes  =  5

Number of cars   =  3(5) = 15  

Now the ratio of his cars to the total model will be  \frac{15}{20}  which reduces to 3/4.

Answer:

3/5

3/10

1/10

30

Step-by-step explanation:

The ratio of wins (6) to the total number of games (10, from adding 6, 3, and 1) is 6/10, and in simplest form is 3/5.

They lost 3 games out of 10, so 3/10, which cannot be simplified further.

They tied 1 game out of 10, so 1/10, which also cannot be simplified.

If the total number is 50, and we have to multiply 10 (our original total) by 5 to get to 50, multiply the numerator of our unsimplified original win/total ratio (6) by 5 as well to get 30. So, they have won 30 games.
