Question

How do you write 45 hundredths as a fraction and decimal

Answer 1

The hundredths place is the the second number to the right of the decimal so as a decimal you would write it like this:
$0.45$
To write it simply as a fraction, it looks like this:
$\frac{45}{100}$
But if you want to simplify it you need to find a least common multiple of both the denominator and numerator. In this case I would choose 5. Divide both the numerator and the denominator by that number.
$\frac{9}{20}$

Answer 2

the decimal is 4500 the fraction form is 4500 over 10
