Subtract: 72 km 200 m − 48 km 600 m

To answer this item, we are to convert the measurement written in km to meters.

               (72 km)(1000 m / 1 km)  + 200 m = 72200 m

               (48 km)(1000 m/ 1 km) + 600 m = 48600m

Then, subtracting will give us an answer of 23600m which when converted back to kilometres will give us an answer of 23 km 600m.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.
