To add decimals, stack vertically, making sure that all of the decimal points exactly line up. Starting at the far right of the stack, add each vertical column of numbers. In the answer, make sure the decimal point lines up exactly with the points above it. To round off a decimal, the final number is dropped. Add 0.004 g + 0.152 g = 0.156 g (thousandths place) to determine the total number of grams the client consumed. When the final number (6) is 5 or greater, drop that number and increase the adjacent number (5) by 1. When you want a number rounded off to the nearest hundredth, look at the number in the thousandth place and follow the rounding off rule. Therefore, 0.156 = 0.16 g.
