The value of $\dfrac{m}{n}$ is $\boxed{\frac{m}{n} = \frac{{49}}{9}}.$

Further explanation:

Given:

The equation is $\dfrac{3}{7}m = \dfrac{7}{3}n.$

Explanation:

We have to find the value of $\dfrac{m}{n}.$

The left hand side of the equation is $\dfrac{3}{7}m.$

The right hand side of the equation is $\dfrac{7}{3}n.$

Consider the left hand side and the right hand side of the equation as A.

The value of m can be obtained as follows,

$\begin{aligned}\frac{3}{7}m&= A\hfill\\m&= \frac{7}{3}A\hfill\\\end{aligned}$

The value of $n$ can be obtained as follows,

$\begin{aligned}\frac{7}{3}n&= A\hfill\\n&= \frac{3}{7}A \hfill\\\end{aligned}$

The value $\dfrac{m}{n}$ can be calculated as follows,

$\begin{aligned}\dfrac{m}{n}&=\dfrac{{\dfrac{7}{3}A}}{{\dfrac{3}{7}A}}\\&= \dfrac{{\dfrac{7}{3}}}{{\dfrac{3}{7}}}\\&= \dfrac{{7 \times 7}}{{3 \times 3}}\\&= \dfrac{{49}}{9}\\\end{aligned}$

The value of $\dfrac{m}{n}\: {\text{is}\: \boxed{\frac{m}{n} = \dfrac{{49}}{9}}.$

Nostrana [21]

Answer:

$6.72

Step-by-step explanation:

The store is selling lemons at $0.56 each. Each lemon yields about 2 tablespoons of juice.How much will it cost to buy enough lemons to make three 9-inch lemon pies, each requiring half a cup of lemon juice?

1 cup = 16 table spoon of juice

half a cup = 8 table spoon of juice

1 pie require half a cup of lemon juice. so 1 pie requires 8 tablespoon of lemon juice

Each lemon yields about 2 tablespoons of juice

2 times 4 = 8

So 4 lemon needed to make a pie

cost of 1 lemon = 0.56

cost of 4 lemons = $0.56 \cdot 4=2.24$

cost of lemon for making 3 pie= $3 \cdot 2.24=6.72$

Murrr4er [49]

Answer:

(a) 23, 35, 28, 33, 5, 12, 40, 25, 20, 18, 1, 16

1, 5, 12, 16, 18, 20 23, 25, 28, 33, 35, 40

n = 12 M = (20 + 23)/ 2 = 21.5

Q1 = (12 + 16) / 2 = 14 Q3 = (28 + 33) /2 = 30.5

(b) 22, 33, 25, 28, 5, 12, 35, 23, 20, 18, 1, 40, 16

1, 5, 12, 16, 18, 20 | 22 | 23, 25, 28, 33, 35, 40

n = 13 M = 22 Q1 = 14 Q3 = 30.5

1, 3, 5, 12, 16, 18, 20, 22, 23, 25, 28, 33, 35, 40

n = 14 M = (20 + 22)/2 = 21 Q1 = 12 Q3 = 28

(d) 20, 28, 23, 25, 3, 5, 30, 22, 18, 40, 16, 35, 1, 33, 12

1, 3, 5, 12, 16, 18, 20 | 22 | 23, 25, 28, 30, 33, 35, 40

n = 15 M = 22 Q1 = 12 Q3 = 30

hope this helps :)
