Question

Determine which solution is correct for solving StartFraction 5 over 7 EndFraction y = 6using reciprocals.

Answer 1

Given:

The equation is:

$\dfrac{5}{7}y=6$

To find:

The solution of the given equation by using the reciprocals.

Solution:

We have,

$\dfrac{5}{7}y=6$

We need to multiply both sides by the reciprocal of $\dfrac{5}{7}$ to isolate the variable x.

The reciprocal of $\dfrac{5}{7}$ is $\dfrac{7}{5}$. So, multiplying both sides by $\dfrac{7}{5}$, we get

$\dfrac{5}{7}y\times \dfrac{7}{5}=6\times \dfrac{7}{5}$

$y=\dfrac{42}{5}$

$y=8.4$

Therefore, the value of y is 8.4.
