Question

The height of this giraffe is two and a half

metres plus half of its height. How tall is the giraffe?

Answer 1

Explanation:

If the height of the giraffe is two and a half metres plus half of its height, the total height is expressed by the equation:

`= 2 (1)/(2) + ((1)/(2) \ of \ 2(1)/(2))`

Simplify the resulting expression

`= 2 (1)/(2) + ((1)/(2) \ of \ 2(1)/(2))\\= (5)/(2) +((1)/(2) \ of \ (5)/(2))\\= (5)/(2) \ + \ (5)/(4)`

Find the LCM

`(5)/(2) + (5)/(4) \\= (10+5)/(4)\\ = (15)/(4)\\ = 3 (3)/(4) metres`

Hence the giraffe is
`3(3)/(4) \ metres \ tall`
