in 128.77°, there are 128° + 0.77°.

now, there are 60 minutes in 1 degree, and 60 seconds in 1 minute.

how many minutes in 0.77°? well, 60 * 0.77, or 46.2 minutes, which is really 46' + 0.2'

we know there are 60 seconds in 1 minute, so, how many seconds in 0.2'? well, 60 * 0.2, or 12 seconds.

so 128.77° is really 128° + 46' + 12", 128°46'12".

Answer:

$\frac{2y-1}{3y+1}$

Step-by-step explanation:

$\frac{2-\frac{1}{y} }{3+\frac{1}{y} }$ ( multiply numerator and denominator by y to clear the fractions )

$\frac{2-\frac{1}{y} }{3+\frac{1}{y} }$ × $\frac{y}{y}$

= $\frac{2y-1}{3y+1}$
