How to solve =\frac{15}{2}" align="absmiddle" class="latex-formula"> and $\frac{1}{4} =\frac{n}{5}$ ???

Answer 1

Answer:

$2n=\dfrac{15}{2}$

Multiply both sides by 2:

$\implies 2 \cdot 2n=2 \cdot \dfrac{15}{2}$

$\implies 4n=15$

Divide both sides by 4:

$\implies \dfrac{4n}{4}=\dfrac{15}{4}$

$\implies n=\dfrac{15}{4}$

$\dfrac14=\dfrac{n}{5}$

Multiply both sides by 5:

$\implies 5 \cdot \dfrac14=5 \cdot \dfrac{n}{5}$

$\implies \dfrac54=n$

$\implies n=\dfrac54$

Answer 2

Answer:

Step-by-step explanation:

2n = 15/2

Divide both sides b y 2:

n = 15/2 / 2

   = 15/2 * 1/2

    = 15/4.

1/4 = n / 5

Multiply both sides by the LCM (20):

20/4 = 20n/5

5 = 4n

n = 5/4.
