Is 0.4 kilometers and ,0.25 kilometers more than a kilometer

No, 0.4 kilometers and 0.25 kilometers are not more than a kilometer instead, they are 400 meters and 250 meters

No, they are not more than a kilometer.


Explanation: If it were to be more, or equal to, a kilometer, it would have a digit, besides 0, in the ones place. 
But, in these numbers, there is not, therefore making those numbers not more, or equal to, a kilometer. 


The first one would be .40, which is not a whole, and the other is .25, which is also not a number. 

Glad I could help, and good luck!

He needs 7.5 yards  of fabric to sell at the craft fair

Step-by-step explanation:

This is unitary method and we can calculate the value of any number of items if we are given one.

1 pillow= 3/4 yards

10 pillows= 3/4 *10

10 pillows= 15/2

10 pillows=  7.5 yards

or another way is convert 3/4 directly into decimal

3/4= 0.75

1 pillow= 0.75 yards

10 pillows= 0.75 *10

10 pillows=  7.5 yards
