Just divide 450 out of 828
450/828= 0.54347
Move the decimal to the right twice
For this case we must simplify the following expression:
By definition of the law of multiplication signs we have to:
Rewriting the expression we have:
We add similar terms taking into account that:
Equal signs are added and the same sign is placed.

The first step to solve this problem is to compute for the
total money of Veronica. You can do this by:
$35 (given to bill) / 20% (percentage of her money given to
Bill) = $175
Since you already know the total money of Veronica, you can
now compute how much she spent to buy books which are 50% of her remaining
money after giving Bill $35.
($175 - $35) x 50% = $70
Therefore, she spent $70 for her books.
$175 – $35 – $70 = $70
Therefore, she has $70 left.

= ( 2 x 3)( 10^4 x 10^3)
= 6 x 10^7
