Answer 2

To solve this problem, we need to perform the operations in the correct order, following the rules of arithmetic.

First, let's convert 7 meters 5 decimeters 3 centimeters to centimeters: 7 meters = 700 centimeters 5 decimeters = 50 centimeters 3 centimeters = 3 centimeters Total = 700 + 50 + 3 = 753 centimeters

Next, let's calculate 3 meters 8 centimeters times 5: 3 meters = 300 centimeters 8 centimeters = 8 centimeters 3 meters 8 centimeters = 300 + 8 = 308 centimeters 308 centimeters times 5 = 1540 centimeters

Finally, let's subtract 753 centimeters from 1540 centimeters to get the answer: 1540 centimeters - 753 centimeters = 787 centimeters

Therefore, 7m-5dm-3cm is equal to 787 centimeters or 7.87 meters.
