Question

.340 in expanded notation

Answer 1

(3 x .1) + (4 x .01)
x is multiplication

Since the 3 is in the tenths place, multiply by 1 tenth, same with the hundredths place, just multiply 4 by 1 hundredth

Answer 2

`0.340=3 * 0.10 + 4 * 0.01`

Explanation:

Expanded notation refers to write a number showing the value of each digit. Hundreds units are multiplied by 100, tens by 10, units by 1, tenths by 0.10, hundredths by 0.01 and thousandths by 0.001.

So, the given number is 0.340 and the expanded notation is

`0.340=3 * 0.10 + 4 * 0.01`

Observe that each digit was multiplied by its value given by its position.
