What is the ratio of girls to boys in a class with 12 girls and 15 boys

The ratio should look like so:

girls : boys

There are 12 girls

There are 15 boys

Let's plug these numbers into the ratio:

12 : 15

Both 12 and 15 have the greatest common factor of 3. This means that it can be reduced by dividing 3 out of 12 and 15

(12 : 15) ÷ 3

4 : 5

Hope this helped!

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
