4. Nine fruit juice bottles contain 4 1/2 litres of fruit juice between them.

brilliants [131]

Answer:

2 $\frac{1}{2}$ litres or 2.5 litres

Step-by-step explanation:

From the question, 9 fruit juice bottles contain 4 $\frac{1}{2}$ litres of fruit juice. Therefore, to find how many litres of fruit juice would be contained in 5 fruit juice bottles, you multiply 5 by 4 $\frac{1}{2}$ litres and you divide the product by 9.

i.e. Let the quantity of the fruit juice for 5 bottles be x.

9 juice bottles ===> 4 $\frac{1}{2}$ litres

5 juice bottles ===> x

∴x = $\frac{5 * 4\frac{1}{2} }{9} litres$

x = $\frac{5 * 4.5}{9} litres$

x = $\frac{22.5}{9} litres$

x = 2.5 litres or 2 $\frac{1}{2}$ litres

Hope this helps!!!

Prove:

Levart [38]

Given the statement, "If $n^2$ is odd, then $n$ is odd," its contrapositive claims that, "If $n$ is not odd, then $n^2$ is not odd."

So assume $n$ is not odd, i.e. $n$ is even. This means there is an integer $k$ for which $n=2k$ . Squaring this gives $n^2=(2k)^2=4k^2$ .

Well, we can write $4k^2=2(2k^2)$ , and $2k^2$ is just another integer, which means $4k^2=(2k)^2=n^2$ must be even.
