X-y=1
x+y=3
You see the y's can cancel out. So add it together and you have:
2x=4
x=2
Now that you have x, plug it in to one of the equations to find y.
I will plug it into the first one.
(2)-y=1
-y=-1
y=1

Divide and write in simplest form.

Answer:

1. $\frac{3}{17}$ (3/17)

2. $\frac{3}{7}$ (3/7)

3. $\frac{45}{184}$ (45/184)

Step-by-step explanation:

1. $\frac{\frac{3}{5} }{3\frac{2}{5}}$ = $\frac{\frac{3}{5} }{\frac{17}{5}}$ = $\frac{\frac{3}{1} }{\frac{17}{1}}$ = $\frac{3}{17}$

2. $\frac{2}{4\frac{2}{3}}$ = $\frac{\frac{2}{1} }{\frac{14}{3}}$ = $\frac{2}{1} /\frac{14}{3}$ = $\frac{2}{1} *\frac{3}{14}$ = $\frac{6}{14}$ = $\frac{3}{7}$

3. $\frac{\frac{5}{4} }{5\frac{1}{9} }$ = $\frac{\frac{5}{4} }{\frac{46}{9}}$ = $\frac{5}{4}/\frac{46}{9}$ = $\frac{5}{2}/\frac{23}{9}$ = $\frac{5}{2}*\frac{9}{23}$ = $\frac{45}{184}$

Hope this helps!
