Your question - Use the proportion (1000mg/1g = 2900mg/x) to convert milligrams to grams. ==================================================================== SOLVING.....
1000mg = 2900mg ------------------------------- 1g = x
We know that to Convert 1000 to 2900 we multiply by 2.9 x2.9 1000mg = 2900mg
So we must do the same on the other side x2.9 1000mg = 2900mg ------------- -------------- 1g = 2.9 x2.9
