HACTEHA [7]

The age of the giraffe when he is 15 feet tall be 1 year 1 month and  16 days.

<h3>What is fraction?</h3>

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
