Answer 1

1) y = 5/28

2) y= 43/60

3) y= 13/55

4) 13/75

Answer 2

$1. \frac{1}{4} +y=\frac{3}7} \\y=\frac{3}{7}- \frac{1}{4}=\frac{12}{28} -\frac{7}{28} =\frac{5}{28} \\2. y+\frac{4}{11} =\frac{3}{5} \\y=\frac{3}{5} -\frac{4}{11}= \frac{33}{55} -\frac{20}{55}= \frac{13}{55} \\3. y-\frac{5}{12} =\frac{3}{10}\\ y=\frac{3}{10} +\frac{5}{12} =\frac{18}{60} +\frac{25}{60} =\frac{43}{60} \\4. \frac{4}{15}+y= \frac{11}{25}\\ y=\frac{11}{25} -\frac{4}{15} =\frac{33}{75} -\frac{20}{75} =\frac{13}{75}$
