(out loud) find the percentages. 15m is what percent of 60m; 3m; 30m; 1.5 km?

 15meter is 25% of 60m

                  15m is 500% of 3m

                   15m is 50% of 30m

                    15m is 1% of 1.5km.

Step-by-step explanation:

Given: 15m is what percentage of 60m; 3m; 30m; 1.5km

To find: Find the percentage.

Formula used: 1 kilometer=1000meter.

Explanation:

         Let  X percentage of 60m =15meter

So,          X% of 60m =15m

               =  15m

Multiply both side by 100.

             60X = 1500m

On dividing both side by 60

               X = 25%

         Let  X percentage of 3m =15meter

So,          X% of 3m =15m

               =  15m

Multiply both side by 100.

             3X = 1500m

On dividing both side by 3

               X = 500%

         Let  X percentage of 30m =15meter

So,          X% of 30m =15m

               =  15m

Multiply both side by 100.

             30X = 1500m

On dividing both side by 30

               X = 50%

         Let  X percentage of 1.5km =15meter

  Convert kilometer into meter by above formula (1.5km=1500meter)

So,          X% of 1500m =15m

               =  15m

Multiply both side by 100.

             1500X = 1500m

On dividing both side by 1500

               X = 1%

Therefore , 15meter is 25% of 60m

                  15m is 500% of 3m

                   15m is 50% of 30m

                    15m is 1% of 1.5km.
