Answer:

  • v = 5.6m

Step-by-step explanation:

<u>Proportional relationship equation:</u>

  • y = kx, where k- constant of proportionality

<u>Use the given point to work out the value of k:</u>

  • 28 = 5k
  • k = 28/5
  • k = 5.6

<u>In our case the equation is:</u>

  • v = 5.6m, where v- volume, m- mass

21 feet to 8 yards write a ratio as a fraction in simplest form without any units
Dmitriy789 [7]

We know, 3 feet = 1 yard.

We have to convert feet to yards to calculate the ratio so that the final answer doesn't have any unit.

Therefore, 21 feet = \frac{21 feet}{3 feet}yards = 7 yards

Thus, the ratio

\frac{21feet}{8yards} =\frac{7yards}{8yards} =\frac{7}{8}

The fraction \frac{7}{8} is already in its simplest form.

Therefore, the given ratio as a fraction in the simplest form without any units is \frac{7}{8}
