A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Giraffe height = 6 feet

Height grew in 7 months= 1.75 feet

Giraffe's height in 7 month = 7.75 feet

Giraffe's height, 1 feet= $\frac{7}{7.75}$ month

= 0.9032 months

Giraffe's height, 15 feet= 0.9032 x 15 month

= 13.548 month

= 13 months 16 days approx.

= 1 year 1 month 16 days

Hence, the age of giraffe will be 1 year, 1 month and 16 days

DanielleElmas [232]

Answer:

-4

Step-by-step explanation:

Use the given value of f(1) to find f(2):

f(2) = f(1) · (-1/2) = (-16)(-1/2) = 8

Now, we can find f(3) using f(2):

f(3) = f(2) · (-1/2) = (8)(-1/2)

f(3) = -4
