How does the property manager check the water meter? (summer homework assigned by the teacher, check the water meter%>_<%)

Look at the reading on the water meter.

X 1 a digit representing a number. The number of the black table x 1 is 5, so the single digit of this reading is 5.

X 10 represents the ten digits of a number. The number of the black table x 10 is 0, so the decimal number of this reading is 0.

X 100 represents the hundredth digit of a number. The number of black table x 100 is 0, so the hundredth of this reading is 0.

X 1000 stands for thousands. The number of black table x 1000 is 0, so the thousand digits in this study are 0.

Since the position of this reading is 5, the number of digits is 0, the number of digits is 0 and the number of digits is 0, so the number should be read as 5.

Four red water meter hands represent readings after the decimal point.

Generally, water is calculated by tons, which means that money is calculated from 1 ton. Therefore, the red table is not as big as 1 ton, so there is no need to record it.
