3y=2.5-1.6
Subtract 1.6 from both sides.
3y=0.9
Subtract 1.6 from 2.5 to get 0.9.
y=\frac{0.9}{3}
Divide both sides by 3.
y=\frac{9}{30}
Expand \frac{0.9}{3} by multiplying both numerator and the denominator by 10.
y=\frac{3}{10}
Reduce the fraction \frac{9}{30} to lowest terms by extracting and canceling out 3.
