22.57 * 10 = 225.7 g

when multiplying by 10 move decimal point one position to the right

anonymous · Answer

oh ok that helps. so i moved it the wrong direction

cwrw238 · Answer

examples

34.5 * 10 = 345

by 100 ,   2 to the right:

23.67 * 100 = 2367

when dividing you move decimal to the left
