Liam had a container of oatmeal that contained 5 and one-half cups of oatmeal. Liam ate StartFraction 4 over 9 EndFraction cup of oatmeal every morning before school for a week. Which is the best estimate of the number of cups of oatmeal that Liam had left in the container at the end of the five-day week?

3 5/18

Step-by-step explanation:

Liam had a container of oatmeal that contained 5 and one-half cups of oatmeal.

= 5 1/2 cups of oatmeal

Liam ate StartFraction 4 over 9 EndFraction cup of oatmeal every morning before school for a week.

= 4/9 cup of oatmeal for a week

Which is the best estimate of the number of cups of oatmeal that Liam had left in the container at the end of the five-day week?

5 1/2 - 5( 4/9)

11/2 - 20/9

= L.C.M of the denominators = 18

= 9 × 11 - 20 × 2/28

= 99 - 40/18

= 59/18

= 3 5/18

The best estimate of the number of cups of oatmeal that Liam had left in the container at the end of the five-day week is

3 5/18 cups of oatmeal

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
