Which fraction is equivalent to 38%?<br> 3/8<br> 9/25<br> 19/50<br> 3 4\5
KonstantinChe [14]
In order to find a fraction, We know that a percentage is out of a 100. This means we can now place our fraction as:

38/100

In order to find the actual fraction, we will want to simplify. Lets find our least common factor and work down from there. Since we know that 2 can go into both of them, lets reduce by 2.

This means our fraction will now look like: 

19/50

Since 19 is a prime number and cannot be divided by anything but 1 and itself, we know that this is our simplified form. 

This means:

19/50 is the fraction equivalent to 38%.

zalisa [80]

Answer:The team won 15 games


Step-by-step explanation:

Given no of soccer games =50

Ratio of wins to losses =3:7

Let no of wins =3x

and no of losses =7x

Now

3x+7x=50

10x=50

Dividing both sides by 10

x=5

So no of wins =3x =3\times5

=15

We found  the answer as 10 parts equals 50

So 3 parts equals 15
