Question

What is 0.368 written in expanded form?

Answer 1

There are two methods that can be used to write 0.368 in expanded form.

Method-1:

Take the first number after the decimal point and divide it by 10. Take the second number after the decimal point and divide it by 100. Take the third number after the decimal point and divide it by 1000. Lastly, add all of them.

$\frac{3}{10} + \frac{6}{100} + \frac{8}{1000} = 0.368$

Method-2:
Multiply first number after decimal point with 0.1; multiply second number after decimal point with 0.01; multiply third number after decimal point with 0.001, and add them all.

(3 * 0.1) + (6 * 0.01) + (8 * 0.001) = 0.368
