padilas [110]

Answer:

$80.106 = 8 * 10 + 0 * 1 + 1 * 0.1 + 0 * 0.01 + 6 * 0.001$

Step-by-step explanation:

Given

80.106

Required

Write in expanded form

First, we need the place value of each digit:

$8-> Tens -> 10\\0-> Units->1\\1-> Tenths->0.1\\0->Hundredths->0.01\\6-> Thousandths->0.001$

Next, we multiply each digit by its place value, to give the expanded form;

$80.106 = 8 * 10 + 0 * 1 + 1 * 0.1 + 0 * 0.01 + 6 * 0.001$
