Question

$(9*100)+(8*10)+(7*\frac{1}{1000} )$

Please convert to decimal

Answer 1

Let's write the products in parentheses as decimals first, then add.

Let's solve:

$(9*100)+(8*10)+(7*\frac{1}{1000} )$

$=900+80+0.007$

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!
