Let's write the products in parentheses as decimals first, then add.
Let's solve:
[tex](9*100)+(8*10)+(7*\frac{1}{1000} )[/tex]
[tex]=900+80+0.007[/tex]
Let's use a place value chart to put 900 + 80 + 0.007 in standard form
Hundreds Tens Ones Tenths Hundredths Thousandths
9 8 0 . 0 0 7
= 980.007
Hope this helps!
