Question

The height of this giraffe is two and a half
metres plus half of its height. How tall is the giraffe?

Answer 1

Answer:

Step-by-step 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:

$= 2 \frac{1}{2} + (\frac{1}{2} \ of \ 2\frac{1}{2})$

Simplify the resulting expression

$= 2 \frac{1}{2} + (\frac{1}{2} \ of \ 2\frac{1}{2})\\= \frac{5}{2} +(\frac{1}{2} \ of \ \frac{5}{2})\\= \frac{5}{2} \ + \ \frac{5}{4}$

Find the LCM

$\frac{5}{2} + \frac{5}{4} \\= \frac{10+5}{4}\\ = \frac{15}{4}\\ = 3 \frac{3}{4} metres$

Hence the giraffe is $3\frac{3}{4} \ metres \ tall$
