The mixed number 4 1/2 is equal to which improper fraction?
A.)8/2
B.)9/2
C.)5/2
D.)4/2

B) 9/2

Step-by-step explanation:

4½ = 4 + ½

= 8/2 + 1/2 = 9/2

9/2

Step-by-step explanation: To write a mixed number as an improper fraction, first multiply the denominator times the whole number, then add the numerator.

So here, we multiply the denominator, 2, times the whole number, 4, then we add the numerator, 1. So we have (2 × 4) + 1 of 8 + 1 which is 9.

Finally, we put our new number over our old denominator and we have our answer, 9/2. There is also an image provided showing my work.

So 4 and 1/2 can be rewritten as the improper fraction 9/2.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

the answer is 8.64
