1. Convert the mixed number 3 1/4 into a decimal.

To convert a mixed number to a decimal, divide the fraction part by the denominator and then add the whole number part.

1/4 = 0.25 (divide 1 by 4)
3 + 0.25 = 3.25

So, 3 1/4 as a decimal is 3.25.

2. Multiply 2/3 by 0.5.

To multiply fractions, multiply the numerators together and then multiply the denominators together.

2/3 * 0.5 = (2*0)/(3*2) = 0/6 = 0

So, 2/3 multiplied by 0.5 is equal to 0.

3. Multiply 4.5 by 2.

To multiply decimals, multiply the numbers as whole numbers and then count the decimal places in the original numbers. Add that many decimal places to the result.

4.5 * 2 = 9

Since 4.5 has one decimal place, the product will also have one decimal place.

So, 4.5 multiplied by 2 is equal to 9.
