Solving Math Problems

To solve the given math problems, let's start with the first one:

Problem 1: 490 cm - 280 cm

To solve this, we simply subtract 280 cm from 490 cm:

490 cm - 280 cm = 210 cm

So, the result is 210 cm.

Now, let's move on to the second problem:

Problem 2: 640 dm - 160 dm

Similar to the first problem, we subtract 160 dm from 640 dm:

640 dm - 160 dm = 480 dm

Therefore, the result is 480 dm.

So, the solutions to the given problems are: 1. 490 cm - 280 cm = 210 cm 2. 640 dm - 160 dm = 480 dm
