Given:
The expression is
.
To find:
The shows the correct way to use the rule ""multiply by the reciprocal"" for the given expression.
Solution:
According to the rule "multiply by the reciprocal", if a,b,c,d are four number, then
![\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cdfrac%7Ba%7D%7Bb%7D%7D%7B%5Cdfrac%7Bc%7D%7Bd%7D%7D%3D%5Cdfrac%7Ba%7D%7Bb%7D%5Ctimes%20%5Cdfrac%7Bd%7D%7Bc%7D)
We have,
![\dfrac{7}{\frac{5}{8}}](https://tex.z-dn.net/?f=%5Cdfrac%7B7%7D%7B%5Cfrac%7B5%7D%7B8%7D%7D)
It can be written as
![\dfrac{7}{\frac{5}{8}}=\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}](https://tex.z-dn.net/?f=%5Cdfrac%7B7%7D%7B%5Cfrac%7B5%7D%7B8%7D%7D%3D%5Cdfrac%7B%5Cdfrac%7B7%7D%7B1%7D%7D%7B%5Cdfrac%7B5%7D%7B8%7D%7D)
Using the rule "multiply by the reciprocal", we get
![\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{7}{1}\times \dfrac{8}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cdfrac%7B7%7D%7B1%7D%7D%7B%5Cdfrac%7B5%7D%7B8%7D%7D%3D%5Cdfrac%7B7%7D%7B1%7D%5Ctimes%20%5Cdfrac%7B8%7D%7B5%7D)
![\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{7\times 8}{1\times 5}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cdfrac%7B7%7D%7B1%7D%7D%7B%5Cdfrac%7B5%7D%7B8%7D%7D%3D%5Cdfrac%7B7%5Ctimes%208%7D%7B1%5Ctimes%205%7D)
![\dfrac{\dfrac{7}{1}}{\dfrac{5}{8}}=\dfrac{56}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cdfrac%7B7%7D%7B1%7D%7D%7B%5Cdfrac%7B5%7D%7B8%7D%7D%3D%5Cdfrac%7B56%7D%7B5%7D)
Therefore, the correct option is D.
Answer:
6 feet
Step-by-step explanation:
Volume = w × h × l
120 = 4 × 5 × l
l = 120 / 20
l = 6 ft
