What is 4.5 expressed as a fraction?

• A. 4/5
• B. 3/2
• C. 9/2
• D. 1/2

Answer: (C)

To convert the decimal 4.5 into a fraction, we can first recognize that 4.5 can be expressed as 4 and 0.5. The whole number part is 4, and the decimal part, 0.5, is equivalent to the fraction 1/2. To combine these, we write 4.5 as: 4.5 = 4 + 0.5 = 4 + 1/2 To express this as an improper fraction, we can convert the whole number 4 into a fraction with a common denominator. The integer 4 can be written as 8/2 (since 4 equals 8 divided by 2). Therefore: 4.5 = 8/2 + 1/2 Now, by combining the fractions: 8/2 + 1/2 = (8 + 1)/2 = 9/2 Thus, 4.5 expressed as a fraction is 9/2. This is why the correct answer is that 4.5 can be expressed as 9/2.

To express this as an improper fraction, we can convert the whole number 4 into a fraction with a common denominator. The integer 4 can be written as 8/2 (since 4 equals 8 divided by 2). Therefore:

4.5 = 8/2 + 1/2

Now, by combining the fractions:

8/2 + 1/2 = (8 + 1)/2 = 9/2

Thus, 4.5 expressed as a fraction is 9/2. This is why the correct answer is that 4.5 can be expressed as 9/2.
