Answer:

Part 1) \frac{1}{2} =\frac{2}{24}

\frac{2}{24} is \frac{1}{12} in reduced form .

\frac{1}{2} =\frac{2}{24}

\frac{1}{2}\neq\frac{1}{12}

These are not proportionate to each other

Part 2) \frac{3}{8}y =\frac{9}{24}y

\frac{9}{24}y is \frac{3}{8}y in reduced form .

So,  \frac{3}{8}y =\frac{9}{24}y

So, these are proportionate to each other .

Part 3) 4 =\frac{64}{16}

\frac{64}{16} is \frac{4}{1} in reduced form .

So,  4 =\frac{64}{16}

So, these are proportionate to each other .

Part 4) \frac{x}{y} =\frac{y}{x}

Since we cannot reduce \frac{x}{y} into \frac{y}{x} and vice versa.

So, These are not proportionate to each other

Part 5) \frac{3z}{x} =\frac{9z}{3x}

\frac{9z}{3x} is \frac{3z}{x} in reduced form .

So, \frac{3z}{x} =\frac{9z}{3x}

So, these are proportionate to each other .

3/8y = 9/24 since 3*3=9 and 8*3=24
4 = 64/16 since 16*4=64
3z/x = 9z/3x since 3z*3=9z and x*3=3x

Step-by-step explanation:

How are we supposed to find volume if you don't enter the other elements I.e width, length and height?

But just in case the formulae for finding volume is to multiply is elements. So to find volume multiply is width, length and height.
