The solution
Detail solution
Given the equation:
$$\frac{64}{y} = 4$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
so we get the equation
$$- \frac{y}{64} = - \frac{1}{4}$$
$$- \frac{y}{64} = - \frac{1}{4}$$
Divide both parts of the equation by -1/64
We get the answer: y = 16
$$\frac{64}{y} = 4$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
a1 = 1
b1 = -1/4
a2 = 1
b2 = -y/64
so we get the equation
$$- \frac{y}{64} = - \frac{1}{4}$$
$$- \frac{y}{64} = - \frac{1}{4}$$
Divide both parts of the equation by -1/64
y = -1/4 / (-1/64)
We get the answer: y = 16
