Question

помогите плиз 5 класс

Answer 1

(3 1/28 + у) – 1 4/7 = 4 15/28
3 1/28 + у – 1 4/7 = 4 15/28
у = 4 15/28 – 3 1/28 + 1 4/7
у = 1 14/28 + 1 16/28
у = 2 30/28
у = 3 2/28
у = 3 1/14

Answer 2

$(3 frac{1}{28}+y )-1 frac{4}{7} =4 frac{15}{28}$
$3 frac{1}{28}+y =4 frac{15}{28}+1 frac{4}{7}=6 frac{3}{28}$
$y =6 frac{3}{28} -3 frac{1}{28}=3frac{2}{28} =3 frac{1}{14}$
