Question

4 1/2 ounces per 3/4 miles _____ ounces per 1 mile

Answer 1

Answer:

6 ounces

Step-by-step explanation:

Create a proportion where x is the number of ounces per 1 mile:

$\frac{4.5}{0.75}$ = $\frac{x}{1}$

Cross multiply and solve for x:

4.5 = 0.75x

6 = x

So, the answer is 6 ounces

Answer 2

6 ounces

Step-by-step explanation:

Let the unknown number be x

$4 \frac{1}{2} \: \: ounces = \frac{3}{4} \: \: miles \\ x = 1 \: \: mile$

Now simply use cross multiplication to solve it

$4 \frac{1}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} = \frac{3x}{4}$

Now make x as the Subject

$\frac{9}{2} = \frac{3x}{4} \\ \frac{9 \times 4}{2 \times 3} = x \\ \frac{36}{6} = x \\ 6 = x$

So the answer is

6 ounces
