Explain how to write numbers in expanded form when the number includes a zero?

Step-by-step explanation:

Expanded notation may be defined as the way of expressing a number by exhibiting its value of each of the digit.

In an expanded notation, the number is always represented as a summation of each of the digit times its place value, while in the expanded form, an addition is used between the place value numbers.

A number containing zero can be written in the expanded form as for example,

509,300

Since digit 5 is 100,000th place, 9 is in 1,000th place and the digit 3 is 100th place, the number can be written as --

5 x 100,000 + 9 x 1,000 + 3 x 100

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
