Multiply 9 books by 55% by doing
9 x .55 = 4.95
We can't have 4.95 books, though so it rounds down to 4 because you can't just add another .05.
Rational. Not whole or integer because its an exact measurement and not irrational because it CAN be expressed as a ratio (fraction, decimal measurement )

3144/9= 349.33
I used a calculator, but you can also solve this by long division (if a calculator isn’t available)
hope this helps!! :)
