Is 1/4 greater than or less than 3/9

Less

Step-by-step explanation: Ok lets make them both have a common denominator. This is 36. So 1/4 is going to be 9/36 and 3/9 is going to be 12/36

1/4 is less than 3/9.

Step-by-step explanation:

Take these fractions into decimal format.

1/4 = 0.25

3/9 = 0.33.

From this, 0.25 < 0.33

So, 1/4 < 3/9, or 1/4 is less than 3/9.

a² + b²= c²

24² + 7² = c²

c= 25

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
