Answer
y = $\frac{7}{3}$
Work Step by Step
To solve, simply cross multiply across the fractions:
Multiply the denominator of one fraction times the numerator of the other and vice versa:
($\frac{3}{7}$)y = 4($\frac{1}{4}$)
$\frac{3}{7}$y = 1
Now, to get y by itself, multiply both sides by the reciprocal of $\frac{3}{7}$, which is $\frac{7}{3}$
$\frac{7}{3}$($\frac{3}{7}$y) = $\frac{7}{3}$(1)
y = $\frac{7}{3}$
