Математика: 7/2х+1/8х 1/6х+1/2х 9/3х-1/4х 3/4х-1/2х 10х-6/7х х-4/5х

крутой1337228 · Answer

7/2х+1/8х = 28/8х + 1/8х = 29/8х = 3 5/8х,

1/6х+1/2х = 1/6х + 3/6х = 4/6х = 2/3х,

9/3х-1/4х = 36/12х - 3/12х = 33/12х = 11/4х = 2 3/4х,

3/4х-1/2х = 3/4х - 2/4х = 1/4х,

10х-6/7х = 9 1/7х,

х-4/5х = 5/5х - 4/5х = 1/5х
