It is already in simplest form
Hope this helps you!
50 times 28, you will get 1400.
If trying to mental calculate, I would :
28=20+8
50 times 20 = 1000
50 times 8 = 400
Then add them up to 1400.
If you use metric conversion (shown below), you will find that 9 meters = 90 cm. Tell me if you need further explanation.
