Question

What decimal is represented by this expanded form?

Answer 1

5 x 10,000 + 3 x 1,000 + 2 x 10 + 8 x 1 + $6 \frac{1}{1000}$ + 4 x $\frac{1}{1000}$

you want to make the $6 \frac{1}{1000}$ into a whole number:
$6 \frac{1}{1000}$ = 6.001

new equation:
5 x 10,000 + 3 x 1,000 + 2 x 10 + 8 x 1 + 6.001 + 4 x $\frac{1}{1000}$
50,000 + 3 x 1,000 + 2 x 10 + 8 x 1 + 6.001 + 4 x $\frac{1}{1000}$
50,000 + 3,000 + 2 x 10 + 8 x 1 + 6.001 + 4 x $\frac{1}{1000}$
50,000 + 3,000 + 20 + 8 x 1 + 6.001 + 4 x $\frac{1}{1000}$
50,000 + 3,000 + 20 + 8 + 6.001 + 4 x $\frac{1}{1000}$
50,000 + 3,000 + 20 + 8 + 6.001 + .004
53,000 + 20 + 8 + 6.001 + .004
53,020 + 8 + 6.001 + .004
53,028 + 6.001 + .004
53,034 + .004
=53,034.005
