So this ratio has 5 parts (the 3 and 2 added make 5).  We take the total games and divide by the total parts of the ratio
20/5=4

We now know that each part of the ratio is equal to 4 games.  So we multiply by the parts

3*4 = 12
2*4 = 8

Therefor our ratio is 12 to 8 or 12 wins to 8 losses

The team won 12 games

Hope that helps.

1) the sum of three consecutive integers even is 3,2,1. find the integers.
BabaBlast [244]

3)The original rational number was 17/12.

4)The age of Ruby and Reshma are 20 and 28 years respectively.

Explanation:

3)Let the numerator be x.

So denominator will be (x - 5)

If we add 5 to numberator then it will be (x + 5)

New number is (x + 5)/(x - 5)=11/6

Solve for X by cross multiplying

6(x + 5)=11(x - 5)

6x + 30=11x - 55

5x=85

x=17

So original rational number was 17/12.

4)The ages of Ruby and Reshma are in the ratio 5:7

So, let the present ages of Ruby and Reshma be 5x and 7x respectively.

Also, it is given that four years from now the ratio of their ages will be 3:4

So, the equation - 5x + 4 / 7x + 3 = 3/4

⇒4(5x+4)=3(7x+4)

⇒20x+16=21x+12

⇒21x−20x=16−12

⇒x=4

⇒5x=20 and 7x=28

The age of Ruby and Reshma are 20 and 28 years respectively.

A horse can run 1 3/8 of a mie in 1 3/5 minute. how long does it take the horse to run 1 mile
mario62 [17]

A horse can run 1 3/8 of a mile in 1 3/5 minute. How long does it take the horse to run 1 mile?

So what i would personally do first is convert the fractions into decimals.

1 3/8= 11/8= 1.375    of a mile  

1 3/5= 8/5 =1.6         of a minute

Now we find the rate of change
